Overview
LYRA-B20 is a privacy layer built natively on Base. It lets you send value, interact with smart contracts, and run AI queries without exposing your activity to the public ledger.
Base is a public blockchain. Every standard transfer and contract call is permanently visible to anyone with a block explorer: the sender address, recipient address, exact amount, and even which AI service your wallet queried. That data does not expire. It accumulates into a permanent, searchable history of your financial and informational behavior.
LYRA routes value and queries through a shielded pool. The public chain sees only valid cryptographic commitments, verified by zero-knowledge proofs. What you did, how much, with whom, and what you asked: none of it appears in the public record. Settlement is still on Base. Speed is still Base speed. Privacy is the only change.
LYRA is built on Base's B20 token standard, Base's enshrined native token interface shipping with the B20 upgrade. B20 provides full composability with the Base ecosystem: DEXes, bridges, wallets. LYRA adds the shielded layer on top. B20 is the foundation; privacy is the protocol.
On public Base
With LYRA-B20
ShieldedGet started
Three steps to go from a standard Base wallet to a fully shielded one. No sign-up, no custodian, no extra configuration.
Connect a Base wallet
Any EIP-1193 wallet on Base works: MetaMask, Coinbase Wallet, Rainbow, or any WalletConnect-enabled app. No sign-up, no email, no KYC. Connect once and you are in.
Get LYRA
Acquire LYRA on any Base DEX (Aerodrome, Uniswap v3 on Base, etc.) or bridge in from another chain using the standard Base bridge. LYRA is the token that powers every shielded action on the protocol.
Private by default
Once your wallet holds LYRA, transfers and contract calls route through the shielded pool automatically. No settings to toggle, no mode to enable. Privacy is the default, not an option.
Mainnet shielding gates open with the Base upgrade wave (see the Network section). Testnet is open now. Join the waitlist for mainnet first access.
Private transfers
Send value on Base without broadcasting your balance, amount, or counterparty to the public ledger.
When you initiate a transfer through LYRA, your funds enter the shielded pool as a cryptographic commitment: a hash that represents "a valid note exists here," with no amount or owner attached. A zero-knowledge proof authorizes the spend without revealing which note is being spent. The recipient withdraws to a fresh address of their choosing, breaking every on-chain link between sender, amount, and recipient.
Proofs are generated client-side in your browser. LYRA never touches your funds. The entire protocol is non-custodial and ERC-20 compatible via the B20 standard, so shielded LYRA works with any Base-native tooling.
What stays private
- Sender address
- Recipient address
- Transfer amount
- Shielded balance
What is still public
- A shielded operation occurred
- Gas spent (by relayer address)
Private transactions
Interact with contracts and dapps without leaking your activity graph to the world.
On a standard wallet, every token approval, DEX swap, DAO vote, and NFT mint is tied to your address and visible forever. Anyone can reconstruct your full financial history from a single wallet address. LYRA routes contract interactions through a shielded execution layer: the call goes through, the outcome settles on Base, but your funding address is not linked to the action in the public record.
A relayer (or Base's native account abstraction layer) submits the call on your behalf. You keep full key custody throughout. LYRA never takes custody of assets. Every shielded transaction is verified by the same consensus rules that secure the rest of Base: valid proofs, valid nonces, valid state transitions.
Example use cases
- Private swap: trade tokens on a Base DEX without exposing trade size or strategy
- Private vote: participate in DAO governance without linking your political activity to your address
- Private mint: mint NFTs or claim airdrops without associating the action with your main wallet
Private AI
Your prompts are some of the most sensitive data you produce. On a normal AI stack, they are logged, analyzed, and used to train future models. LYRA eliminates that entirely.
01Private search
Query an AI-powered search engine with no logging, no profiling, and no tie to your identity. The pipeline is stateless: each query arrives encrypted, is processed in isolation, and returns a response. Nothing is retained between sessions. Nothing is linked to a wallet address. No usage patterns are stored or sold.
Use it for on-chain data lookups, token research, protocol documentation, or any general knowledge query you would rather not broadcast.
02Private LLM
Prompts leave your device encrypted. They are processed in an isolated, ephemeral context that is destroyed the moment the response is returned. Nothing is stored server-side. Responses stream back end-to-end without touching any persistent log. Your data is never used for model training, fine-tuning, or analytics.
Access is gated by LYRA balance. Hold LYRA in your shielded wallet to unlock both the private LLM and private search interfaces. No separate subscription, no separate account.
The B20 standard
B20 is Base's enshrined native token standard: fully ERC-20 compatible, with native execution at the protocol level rather than as a deployed contract.
The B20 upgrade bakes the token standard into Base's execution layer. The effect is lower gas costs for token operations, tighter composability with other Base primitives, and first-class wallet and tooling support from day one. Any existing ERC-20-compatible wallet, DEX, bridge, or indexer works with a B20 token without any changes. LYRA is a B20 token.
That means LYRA lists on Base DEXes, bridges to other chains through standard Base bridges, and appears in any wallet that supports Base. The composability comes from the B20 standard. The privacy comes from the LYRA protocol layer built on top.
B20 itself is a public standard. Transactions using it are visible on Base like any other token transfer. Privacy is LYRA's layer on top, not a property of the B20 standard. Only transactions routed through the LYRA shielded pool benefit from confidentiality.
Network and mainnet
LYRA is live on Base testnet. The waitlist is open. Shielded mainnet gates open with Base's upgrade wave, once B20 ships.
LYRA does not launch in isolation. It is built on top of Base's infrastructure upgrade cycle: the B20 token standard and native account abstraction are both foundational to what LYRA delivers. The timeline below shows how each milestone connects.
Live on Base testnet
Shielded transfers, private contract calls, and private AI are available on Base testnet. Waitlist is open.
Base ships the B20 standard
Base's enshrined native token standard goes live. LYRA's shielded layer builds directly on it for deep protocol composability.
Base native account abstraction
Base ships native account abstraction, enabling gasless and sponsored private actions. LYRA integrates on launch.
LYRA shielded mainnet gates open
Full shielded mainnet access. Waitlist members get priority. Private transfers, private transactions, and private AI at scale on Base.
FAQ
Is my balance visible on-chain?
No. Shielded balances are not visible on the public Base ledger. Observers see only cryptographic commitments: proofs that a valid operation occurred. Actual amounts and counterparty addresses are never revealed.
Do you log my AI prompts or search queries?
No. LYRA operates a stateless, encrypted pipeline with zero retention by default. Prompts are processed in isolated ephemeral contexts that are destroyed when the session ends. Your data is never stored server-side, indexed, or used for model training.
Is LYRA on mainnet yet?
LYRA is live on Base testnet today. Shielded mainnet gates open with Base's upgrade wave, once B20 ships. No public date is set yet. Join the waitlist now to get first access when they do.
Is LYRA custodial?
No. LYRA is fully non-custodial. Zero-knowledge proofs are generated client-side in your browser. LYRA never holds, touches, or has access to your funds at any point in the flow.
Is B20 itself private?
No. B20 is Base's public token standard, fully visible on-chain like any ERC-20. Privacy is LYRA's layer on top. Only transactions routed through the LYRA shielded pool benefit from confidentiality. B20 provides composability; LYRA provides privacy.
Which wallets are supported?
Any EIP-1193-compatible wallet that connects to Base: MetaMask, Coinbase Wallet, Rainbow, and any WalletConnect-enabled app. If it works on Base, it works with LYRA.
How does the waitlist work?
Join at lyra-b20.site or reach out at info@lyra-b20.site. Waitlist members get first access when shielded mainnet gates open. There is no cost to join and no commitment required.
