Table of Contents

CAIP-10

For context, see the CAIP-10 specification.

Rationale

While Ethereum “accounts” were the unstated norm in the definition of CAIP-10, the “script hashes” addressing schemed defined by BIP13 map well enough to “account”-model blockchains that these can be described by a CAIP-10 reference.

Syntax

See Specification section of BIP13.

Backwards Compatibility

Previously, the legacy CAIP-10 schema was defined by appending as suffix the CAIP-2 chainId delimited by the at sign (@)
