Addresses - Biconomy Docs

Contracts

Same addresses on Base (8453) and Base Sepolia (84532).

Contract	Address	Used by
`PropAMMExecutor`	`0x0000006f9bBA066e4efda2e0CAbE4FF8cf9030aC`	makers: EIP-712 `verifyingContract` and the provider’s `approvedExecutor`
`PropAMMVenue`	`0x0000009E5F98cDB4dd1E1d2E15B220217c88B3b8`	aggregators: `quote`, `quoteFillable` and `swap`

Stream endpoints

Environment	WebSocket	Chains
Staging	`wss://propamm-staging.biconomy.io/v1/ws`	Base Sepolia (84532)
Production	`wss://propamm.biconomy.io/v1/ws`	Base (8453)

Both endpoints require an API key in the x-api-key header of the connection request; without one the server refuses the connection with HTTP 401. To move from staging to production, change the endpoint, chainId and token addresses.

EIP-712 domain

Field	Value
`name`	`PropAMMExecutor`
`version`	`2`
`chainId`	the chain the ladder lives on
`verifyingContract`	`0x0000006f9bBA066e4efda2e0CAbE4FF8cf9030aC`

The executor exposes DOMAIN_SEPARATOR() and the digests your key signs (ladderDigest, offsetLadderDigest, anchorBatchDigest, controlsDigest) as views. Structs are in the Message reference.
