Decode

@erc7730/sdk@0.9.0

Primary wallet surface:

Function	When
`decodeTransaction`	`eth_sendTransaction` / `eth_signTransaction` (Multicall3 / Safe CALL → `children`)
`decodeTypedData`	`eth_signTypedData`
`decodeBatch`	EIP-5792 `wallet_sendCalls`
`decodeUserOp`	ERC-4337 Simple Account `execute` / `executeBatch`
`format` / `formatTypedData`	Compat aliases of `decode*`

Signatures and types: see the generated API.

What to show

Prefer interpolatedIntent when present (spec option 1).
Otherwise show intent + fields.
Surface warnings (e.g. infinite_approval, NO_TRUSTED_ATTESTATION, interpolation_failed).
Nested format: "calldata" fields expose field.embedded. Multicall3 / Safe CALL / UserOp expose children: DecodedOperation[] with per-child source and trust.
locale only formats numbers and dates. Descriptor intent strings are never translated.

`format` aliases

format / formatTypedData call the same decode pipeline. When a registry is set and no trust policy is passed, they default to officialOrLocalPolicy(). DecodedOperation remains the source of truth — not Sourcify’s DisplayModel.

For production wallets, pass trust: officialOnlyPolicy() (or attestedPolicy) explicitly on decode* rather than relying on the compat default.

Context matching

Before a descriptor is applied, matchContext must succeed: deployments, EIP-1967 / EIP-1167, factory deployEvent logs, EIP-712 domain / domainSeparator. A familiar selector on an unbound address is inferred / low — never high under official-only.

Factory log range

Provider.getLogs defaults to fromBlock: "earliest" / toBlock: "latest". Pass bounded ranges on public RPCs via DecodeOptions / MatchContextOptions.

ClearSigner

createClearSigner(options?) binds DecodeOptions for repeated calls. ClearSigner.decode is a deprecated alias of decodeTransaction and returns DecodedOperation.
