Summary

Movement is a Layer 2 network built on Move, featuring parallel execution for high throughput. This PR establishes the movement namespace for identifying Movement-based chains and accounts.

Chain Identification (CAIP-2)

Chains in the Movement namespace are identified by their numeric chain_id, which is assigned at genesis and requires no transformation to be used as a CAIP-2 reference.

Network	Chain ID	CAIP-2 Identifier
Mainnet	126	movement:126
Testnet	250	movement:250

Account Identification (CAIP-10)

Movement accounts are identified by 32-byte hexadecimal addresses with a 0x prefix. Account identifiers follow the format movement:<chain_id>:<address>.

Example: movement:126:0xd5fb7899ac1e3b4a51bfbf0dcafaa78453bb8e9a64a93a8e47fedad6b8c48171

Resolution

Chain IDs can be resolved by querying the REST API of any Movement fullnode:

curl https://mainnet.movementnetwork.xyz/v1

The chain_id field in the response provides the identifier.

Account existence can be verified via:

curl https://mainnet.movementnetwork.xyz/v1/accounts/<address>
