Ethereum's fastest Layer 2 deserves a wallet without seed phrases.

Base is the largest Ethereum Layer 2 by DeFi activity. Built by Coinbase using the OP Stack from Optimism, Base processes over 12 million transactions daily, holds more than $4.6 billion in DeFi TVL, and accounts for roughly 46% of all Layer 2 DeFi value locked. That is more than Arbitrum, Optimism, Polygon, and most other Layer 2s combined. Base is not just another rollup. It is the chain that brings Coinbase's 110 million verified users on-chain.

Gas fees on Base are typically under one cent. Flashblocks reduce effective block times from 2 seconds to 200 milliseconds, making Base one of the fastest EVM chains available. Transactions confirm almost instantly and cost almost nothing. That combination of speed and cost has attracted a thriving ecosystem of DeFi protocols, NFT platforms, SocialFi applications, and on-chain content tools.

bonuz is a self-custodial Base wallet that supports the entire Base ecosystem without seed phrases. No browser extensions. No manual RPC configuration. Base is ready the moment you open the app.

The Base DeFi ecosystem is deep. Aerodrome Finance is the largest DEX on Base, with over $600 million in TVL and a ve(3,3) tokenomics model that directs trading fees to governance participants. Morpho powers lending on Base with over $966 million in TVL, integrated directly with Coinbase so users can borrow USDC against crypto collateral. Uniswap, Aave, Compound, Curve, and Seamless Protocol all run on Base with full functionality. Connect to any of them from bonuz via WalletConnect v2.

USDC on Base is native. Circle issues USDC directly on Base, fully backed and redeemable 1:1 for US dollars. Base holds over $4.2 billion in stablecoin capitalization, with USDC making up the vast majority. That makes Base one of the largest stablecoin networks across all chains, not just Layer 2s.

Built-in swaps in bonuz route through multiple DEX aggregators, primarily LI.FI along with 1inch, Uniswap, PancakeSwap, Jupiter, and others. Cross-chain swaps let you move assets between Base and Ethereum, Solana, BNB Chain, Polygon, Arbitrum, and Avalanche without leaving the app. Need to bridge ETH from Ethereum to Base? Do it in bonuz. Need to move USDC from Base to Polygon? Same.

Base is part of the Optimism Superchain, a network of interoperable Layer 2 chains that share security infrastructure and will eventually enable seamless cross-chain communication. As the Superchain matures, assets and messages will flow between Base, Optimism mainnet, Unichain, World Chain, and other member chains with minimal friction.

Security is layered. bonuz uses MPC/TSS (Multi-Party Computation / Threshold Signature Scheme) key technology to split your private key into encrypted shares. No seed phrase to lose. No single point of failure. Sign in with your email, Google, or Apple ID. Your wallet is ready in seconds. If you lose your phone, sign in on a new device. If you want to export your key for use in another wallet, you can. Hacken audited smart contracts score 10/10. Halborn and NCC Group verified key infrastructure. SOC 2 Type II certified operations. Face ID, a separate sending PIN for every outgoing transaction, and configurable auto-lock.

Base inherits Ethereum's security because all transactions are ultimately posted to Ethereum mainnet for final settlement. Base achieved Stage 1 decentralization in April 2025 with permissionless fault proofs. However, Coinbase currently operates the sole sequencer, which is a centralization trade-off shared by most Optimistic Rollups.

Self-Custodial Security for Base

Your Base wallet. Your keys. Your rules.

bonuz is self-custodial by design. When you interact with Aerodrome, Morpho, Uniswap, or any other Base protocol, bonuz holds your keys and signs your transactions. bonuz cannot access your funds, reverse your transactions, or interact with protocols on your behalf.

How your keys are protected:

Your private key is secured with MPC/TSS (Multi-Party Computation / Threshold Signature Scheme) technology. Instead of storing your key as one piece, bonuz splits it into encrypted shares distributed across multiple secure environments. No single share is enough to access your wallet. The MPC infrastructure is powered by Web3Auth, trusted by over 50 million users globally.

bonuz uses HD (Hierarchical Deterministic) wallet infrastructure on top of MPC. Your Base addresses use m/44'/60'/0'/0' (the same derivation path as Ethereum, since Base is EVM-compatible). Standard derivation paths, fully compatible with the broader ecosystem.

Independently audited. Independently verified.

A note on Base network security:

Base inherits Ethereum's security through its Optimistic Rollup design. All Base transactions are posted to Ethereum mainnet for final settlement. In April 2025, Base achieved Stage 1 decentralization with permissionless fault proofs. However, Coinbase currently operates the sole sequencer for transaction ordering. If the sequencer experiences downtime, transactions cannot be processed until it is restored. This is a centralization trade-off common to most Optimistic Rollups at this stage. Base has stated goals to progress toward further decentralization.

Frequently Asked Questions

Everything you need to know about Base and bonuz

What is Base?
Base is an Ethereum Layer 2 blockchain built by Coinbase using the OP Stack from Optimism. It processes transactions off Ethereum mainnet, then posts the data back to Ethereum for security. This means you get Ethereum-grade security with sub-cent gas fees and 200-millisecond block confirmations via Flashblocks. Base has no native token. Gas fees are paid in ETH. Base is the largest Layer 2 by DeFi TVL, holding over $4.6 billion and accounting for roughly 46% of all L2 DeFi activity. It processes over 12 million transactions daily.
What is a Base wallet?
A Base wallet is a crypto wallet that supports the Base network. Since Base is EVM-compatible, any wallet that supports Ethereum can also support Base by adding the Base network. bonuz supports Base natively, so all Base tokens, DeFi protocols, and dApps are accessible from the app without any manual network configuration. bonuz also supports cross-chain swaps between Base and other chains like Ethereum, Solana, BNB Chain, Polygon, and Arbitrum.
Does bonuz support Base?
Yes. bonuz supports Base natively. You can send, receive, swap, and store any token on Base. You can connect to Base DeFi protocols like Aerodrome, Morpho, Uniswap, Aave, and Compound via WalletConnect v2. You can also swap tokens between Base and other supported chains like Ethereum, Solana, BNB Chain, Polygon, and Arbitrum directly inside the bonuz app. No manual RPC configuration required.
How much are gas fees on Base?
Gas fees on Base are typically under one cent for standard transactions like token transfers and swaps. This is dramatically cheaper than Ethereum mainnet, where gas can cost several dollars during busy periods. Base achieves low fees by processing transactions off-chain in batches and posting compressed data to Ethereum for final settlement. Gas fees are paid in ETH. bonuz also sponsors gas for many core ecosystem actions like quests and bonuz ID interactions.
What are Flashblocks on Base?
Flashblocks are a Base technology that reduces effective block times from 2 seconds to 200 milliseconds, making Base one of the fastest EVM chains available. Flashblocks are partial blocks streamed every 200ms by the block builder, giving users near-instant transaction confirmations. Developed in collaboration with Flashbots, Flashblocks launched on Base mainnet in mid-2025. They also include revert protection, which filters out failing transactions before they are included, saving users from paying gas on failed transactions.
What is the Superchain?
The Superchain is Optimism's network of interoperable Layer 2 chains built using the OP Stack. Base is part of the Superchain alongside Optimism mainnet, World Chain, Unichain, INK, and Soneium. Superchain chains share security infrastructure and are working toward cross-chain interoperability, which will allow seamless asset and message passing between member chains. This means Base benefits from shared upgrades and a growing network of connected Layer 2s.
What DeFi protocols are on Base?
Base has a rapidly growing DeFi ecosystem. The top protocols include Aerodrome (the largest DEX on Base by TVL, with over $600 million locked), Morpho (lending and borrowing, with over $966 million in TVL on Base), Uniswap (multi-chain DEX), Aave (lending), Compound (lending), Seamless Protocol (native Base lending), and Curve (stablecoin swaps). You can connect to all of these via WalletConnect v2 through bonuz.
How do I bridge assets to Base?
bonuz includes built-in cross-chain swaps powered by LI.FI and other aggregators. You can move ETH, USDC, or any supported token from Ethereum, Polygon, Arbitrum, BNB Chain, or other chains to Base directly inside the bonuz app. No separate bridge interface needed. Note that bridging from Base back to Ethereum mainnet via the official Optimistic Rollup bridge takes up to 7 days due to the challenge period. bonuz uses third-party liquidity routes that typically complete in minutes.
Is USDC native on Base?
Yes. Circle launched native USDC on Base, meaning USDC on Base is issued directly by Circle rather than bridged from Ethereum. Native USDC on Base is fully backed and redeemable 1:1 for US dollars. Base has over $4.2 billion in stablecoin capitalization, with USDC accounting for the vast majority. This makes Base one of the largest stablecoin networks among all Layer 2s, even exceeding many Layer 1 chains.
Does Base have a token?
No. Base does not currently have a native token. Gas fees on Base are paid in ETH. In September 2025, Base creator Jesse Pollak confirmed that the team is exploring a network token, but no specific details regarding distribution, utility, or launch date have been announced. bonuz will support any Base token if and when it launches.
Is Base safe?
Base inherits Ethereum's security because all Base transactions are ultimately posted to Ethereum mainnet for final settlement. In April 2025, Base achieved Stage 1 decentralization with permissionless fault proofs, allowing anyone to challenge invalid state transitions. However, Coinbase currently operates the sole sequencer for Base, which introduces a degree of centralization. If the sequencer goes down, users cannot submit transactions until it is restored. This is a known trade-off shared by most Optimistic Rollups.
What is Aerodrome on Base?
Aerodrome Finance is the largest decentralized exchange on Base by TVL. It uses a ve(3,3) tokenomics model where users lock AERO tokens for voting power and earn trading fees. Aerodrome is the primary liquidity hub for the entire Base ecosystem and ranks among the top DEXs across all EVM chains by volume and fees. In late 2025, Aerodrome merged with Velodrome (its Optimism counterpart) to form Aero, a unified trading platform expanding to Ethereum mainnet in 2026.
How does bonuz compare to the Base App (Coinbase Wallet)?
Both are self-custodial wallets that support Base. Key differences: bonuz uses MPC technology instead of seed phrases by default, supports all major chains (Ethereum, Solana, BNB Chain, Polygon, Arbitrum, Avalanche, and more) alongside Base, has a Hacken 10/10 audit score, and is available in 24 languages. The Base App (formerly Coinbase Wallet) is tightly integrated with the Coinbase exchange, includes built-in social features via Farcaster and Zora, and offers direct access to Coinbase-specific features like USDC yield and crypto borrowing via Morpho.
Can I use bonuz for NFTs on Base?
Yes. bonuz supports ERC-721 and ERC-1155 NFTs on Base. You can view, send, and receive NFTs created on Base, including those minted through platforms like Zora. The Base ecosystem has a growing NFT and creator economy, with Zora enabling content tokenization and Farcaster powering decentralized social features that integrate with on-chain assets.
Do I need seed phrases for a Base wallet?
Not with bonuz. bonuz uses MPC (Multi-Party Computation) key technology instead of a 12-word seed phrase. Your private key is split into encrypted shares distributed across multiple secure environments. You sign in with your email, Google, or Apple ID. If you lose your phone, sign in on a new device and everything is restored. You can optionally export your private key or seed phrase at any time for use in another wallet.
