contracts namespace describes each registry protocol’s contracts: per-chain addresses, each bound to the ABI the registry checked against the deployed code. contracts.on(chain) returns typed accessors (contracts.on("base").Uniswap.UniversalRouter) whose methods build ContractCall objects you run with your own viem client.

contracts.addressOn
Function · @eco-incorp/sauce
The sparse-map accessor, bigint-aware - never index perChainAddress by a raw chain id directly.
contracts.contractsOnChain
Function · @eco-incorp/sauce
REVERSE INDEX: every returned descriptor is guaranteed to have an address on chain. kind:“interface” descriptors never appear here (reach them via listInterfaces()).
contracts.describeContract
Function · @eco-incorp/sauce
THE thin resolver: (chain, protocol, contract) -> address + abi + methods for that chain, or undefined.
contracts.descriptorChains
Function · @eco-incorp/sauce
Resolved CanonicalChain records (not raw slugs) for every chain this descriptor has an address on.
contracts.getDescriptor
Function · @eco-incorp/sauce
Chain-free lookup: the descriptor is the chain-INDEPENDENT object; ResolvedContract (describeContract) is its chain-bound view.
contracts.listContracts
Function · @eco-incorp/sauce
Forward index: protocol (slug, or normalized ProtocolInfo.name) -> its descriptors.
contracts.listDescriptors
Function · @eco-incorp/sauce
The whole flat registry, stable order.
contracts.listInterfaces
Function · @eco-incorp/sauce
kind:“interface” descriptors (erc20, erc4626 in the starter set): ABI + methods, no fixed address.
contracts.methodOf
Function · @eco-incorp/sauce
Name-keyed method lookup. An overloaded name’s overloads take different numbers of arguments
(the linkage test holds every descriptor to that), so arity names exactly one of them. Without
it, the first overload the ABI declares is returned.
contracts.protocolsOnChain
Function · @eco-incorp/sauce
The protocols with a contract that has an address on chain, each once, as ProtocolInfo records in registry order; an unknown chain returns an empty list. It reads the contracts registry’s descriptors, where getProtocolsByChain(chainId) reads the protocol catalog.
contracts.requireContract
Function · @eco-incorp/sauce
Throwing sibling of describeContract, mirroring requireChain’s “here is the known set” error style.
contracts.selectorOf
Function · @eco-incorp/sauce
