AssetChain is a permissionless, non-custodial bridge that moves custom BNB Smart Chain ERC-20s to Base. It locks a portion of a token in an isolated vault on BSC and mints a 1:1 representation on Base (e.g. CTB on Base), where it can be used with PayDirect and Coinbase CDP.

Built on LayerZero OFT v2. Reserves are held by contract logic (trustless 1:1); admin is governed by a Gnosis Safe multisig.

1. Onboard — a BSC token is validated as a clean ERC-20; its isolated vault (BSC) and OFT (Base) are deployed.
2. Bridge in — lock X tokens in the vault on BSC → X are minted on Base, 1:1 (minus fees).
3. Bridge out — burn on Base → unlock on BSC.

Base supply can never exceed what's locked on BSC. Each token has its own vault, so one token can never affect another's backing.

Onboarding is open to anyone. The on-chain TokenValidator is the safety gate — it checks standard metadata, non-zero supply, and runs a transfer round-trip to reject fee-on-transfer / rebasing tokens (which would break the 1:1 lock). A one-time native onboarding fee (~$25) covers deploy gas and deters spam.

Upgradeable or pausable source tokens are flagged for off-chain monitoring.

Connect a wallet, pick an onboarded token, choose a direction and amount. You pay the bridge fee (below) plus the LayerZero messaging gas, quoted at send. Delivery is typically a couple of minutes via LayerZero.

• Bridge fee: 0.30% of the bridged amount (in the token) + a small flat native surcharge.
• Pass-through: LayerZero messaging gas (cost, not revenue).
• Onboarding: one-time ~$25 native, per token.
• Exemptions: operator / PayDirect treasury addresses are fee-exempt. All fees are per-token configurable by governance.

Three separated tiers:

• Reserves — locked by contract code; nobody (not even the Safe) can move backing.
• Governance — a Gnosis Safe (3-of-5, both chains) controls fees, caps, pause, peers, and the fee treasury.
• Operations — agent/PayDirect keys handle Base-side payments only; zero bridge-admin power.

Pre-audit, testnet-first. Not deployed to mainnet without an audit.

Do I bridge my whole supply? No — only the portion you want on Base. The vault holds exactly what's bridged.

Is it custodial? No — you hold your own Base tokens.

What if my token has a transfer tax? The validator rejects it (the 1:1 lock requires a clean ERC-20).
