Smart contracts

Each chain runs the same set of contracts. The two escrows hold the traders’ funds; the rest check signatures and proofs, record events, and handle the paths a trade takes when it doesn’t settle normally.

What each contract does

Contract	Role
`AdManager`	maker escrow: ads, liquidity, locks, the co-signed payout to the bridger, cancels and disputes. Its clock decides how a trade ends.
`OrderPortal`	bridger escrow: orders and deposits, the co-signed payout to the maker. It follows the outcome the `AdManager` proves.
`MerkleManager`	the append-only Merkle Mountain Range of trade events on this chain
`Verifier`	checks the zero-knowledge proof of an event on the other chain
`CounterpartyVerifier`	checks both traders’ combined BLS co-signature at payout
`BLSKeyRegistry`	each wallet’s settlement keys, with proof of possession
`RootAnchor`	the other chain’s Merkle roots, used by cancels, forfeits and disputes
`DisputeManager`	dispute filing, bonds and rulings. It never moves escrow funds.
`Registrar`	registration of a key by proof from the account’s home chain. Deployed, not active yet.
`wNativeToken`	wrapped native token for native-asset ads and dispute bonds

On Ethereum, a few more deployments support these: ProofBridgeUtils (shared order and fee logic, a linked library), Poseidon2Yul (the hash the Merkle tree uses), SCL_EIP6565 (ed25519 verification, so a Stellar wallet’s signature can be checked on Ethereum), and the agent contracts (AgentPolicy, AgentPolicyCodec, CustodyAccountFactory). On Stellar, agent accounts are deployed per maker from a published wasm hash.

The contracts have not been audited yet. An audit is planned for T3, backed by the Stellar Community Fund.

Route tokens

Each pair is routed in both directions.

Pair	Sepolia	Stellar Testnet
XLM	WXLM (ERC-20, 18 decimals) `0xba03…414c`	XLM (native, 7 decimals)
ETH	ETH (native, 18 decimals)	wETH (SEP-41, 7 decimals) `CB73…JVLM`
PB	PB (ERC-20, 18 decimals) `0x4074…59B`	PB (SEP-41, 7 decimals) `CC2R…JJIS`

Settings

The same on both chains.

Setting	Value
Bridge fee	0.3% to the maker, 0.2% to the protocol
Shortest order window	20 minutes
Cancel window after the deadline	30 minutes
Anchor delay	5 minutes
Dispute challenge period	1 hour
Dispute bond	0.001 WETH on Sepolia, 1 XLM on Stellar

Addresses change when a deployment is replaced. This page follows the deployment manifests in the ProofBridge repo, which are the source of truth.
