Crate clear_signing 

ERC-7730 v2 clear signing library — decodes and formats contract calldata and EIP-712 typed data for human-readable display using JSON descriptors.

Entry points: format_calldata(), format_typed_data().

Modules

decoder

Solidity function signature parsing and ABI calldata decoding. No JSON ABI needed — signatures are parsed directly from descriptor format keys.

eip712

EIP-712 typed data formatting — parses structured typed data and produces a DisplayModel using the same descriptor format as calldata.

engine

Formatting pipeline: resolves display fields, formats decoded values, and produces a DisplayModel with labeled entries for wallet UIs.

error

Error types for decoding, resolution, and rendering failures.

merge

JSON-level merge for ERC-7730 includes mechanism.

outcome

provider

Unified async data provider trait for external data resolution.

resolver

Pluggable descriptor resolution facade.

token

Token metadata types and built-in providers. Uses CAIP-19 keys (eip155:{chain}/erc20:{addr}) for cross-chain lookups.

types

Data model types for ERC-7730 descriptors: context, display, metadata.

uniffi_compat

Structs

TransactionContext

Transaction context for calldata formatting.

Functions

format_calldata

Format contract calldata for clear signing display.

format_typed_data

Format EIP-712 typed data for clear signing display.
