_**Annex O is an initial technical candidate registry for P24 as of 19 August 2026. “Priority A/B” is implementation priority only. No external coin becomes ACTIVE merely by appearing in this table. Every activation requires CP-53 to CP-57, a Coin Integration Profile, a coin-specific Registrar, REGISTRY READY and SPLIT READY status, and a COIN x PRODUCT x JURISDICTION record.**_

_**Technical verification basis**_

_**The candidate registry was cross-checked against primary protocol/core documentation where available, including Bitcoin Core, Ethereum, BNB Chain, XRP Ledger, Solana, Cardano, TRON, Stellar, Avalanche, Hedera, Polkadot, Algorand, Sui, NEAR, Aptos, Cosmos Hub, Tezos/Octez, Kaspa, TON and Hyperliquid documentation, plus official/core wallet repositories for Bitcoin-family and related chains. Final production onboarding requires fresh source verification under CP-53.**_
