Wholesale Tokenized Settlement Fit Diagnostic
Grade your firm or desk A–F across six dimensions for wholesale tokenized settlement — the cash/money layer, distinct from Wave 8 Canton's asset layer. Covers settlement-asset type, finality regime, cross-network atomicity, asset-leg readiness, deposit-token issuer, intraday liquidity, and reconciliation controls. Routes to the right Wave-13 chain. Client-side, zero-egress; every run emits a hash-anchored OpenChainGraph v0.4 artifact.
Educational diagnostic — not settlement, legal, or financial advice · Hard deadlines: DTCC full production Oct 2026 · ECB Pontes end-Q3 2026

Solana DvP profile (additive note)
- Trust model. The Solana Foundation DvP program is a bilateral two-escrow swap. A third-party settlement authority is the only signer that can settle or cancel, and it cannot redirect proceeds. Matching, pricing, netting, partial fills and any off-ledger leg are outside the program (program docs, retrieved 2026-10-16).
- Escrow per leg. Each party funds its own escrow token account by a plain token transfer; the program-owned record is 458 bytes, so a funder should check owner, length, parties, mints, amounts, timestamps and destinations before funding (README State @df9919ed, SwapDvp struct @df9919ed).
- Finalized is not legal finality. The doc treats an on-chain
finalizedcommitment as the settlement point and states that legal finality is contractual. Legal finality stays with the governing contracts and the regimes classified on this page set. - Eligibility sits in the mint controls. The program has no allowlist or KYC. Token-2022 mint controls (PermanentDelegate, Pausable, DefaultAccountState, freeze authority, Token ACL) are accepted by the program and carry counterparty risk for the funder; they are the eligibility layer, not the program.
- Transfer-fee mints are rejected. The program refuses mints with TransferFeeConfig, InterestBearingConfig, ScaledUiAmountConfig or NonTransferable (blocked extensions @df9919ed). For the transfer-fee case see ART-715 Token-2022 Transfer Fee Reconciler.
