A parent index across AINumbers' token-standard tools, organized by the standard they implement rather than by regulation or asset class: vault standards for share-based custody, signature and authorization standards for agent and credential-bound actions, interface and royalty standards for transferable and licensable tokens, and the compliance and classification tools that decide what a token legally is. This hub is a map, not a fifth silo: the deep-dive hubs for tokenization infrastructure, stablecoins, MiCA, and crypto tax reporting stay where they are and are cross-linked below.
Each row below is a task, not a section label. Pick the one closest to what you're doing and jump straight to the relevant tools.
Tokenized collateral eligibility, fund-share validation, collateral swaps, security lifecycle, and repo haircut math for share-based custody positions.
Payment and checkout mandate builders, HTTP message signature decoding, MCP OAuth audits, verifiable credential structural checks, and provenance manifests.
NFT metadata validation, IPFS CID computation, royalty-split configs, Creative Commons and ccREL licensing, and IP license flavor selection.
Security/commodity/e-money classification, MiCA white papers and reporting calendars, GENIUS Act issuer mapping, ERC-3643/1400 compliance pre-checks, and permissioned-chain config audits.
Tools for share-based custody positions: fund shares, repo collateral, and collateral swaps priced and validated the way a vault standard expects.
Classify tokenized assets for DTC/Fed eligibility, Basel HQLA tier, and transfer restrictions, for DvP, repo, margin, and fund workflows.
Open ToolValidate tokenized MMF/CNAV/LVNAV/VNAV fund shares as collateral under SEC Rule 2a-7, EU MMFR, and Basel LCR HQLA exclusion rules.
Open ToolValidate a collateral swap (upgrade/downgrade) under GMSLA, GMRA, and SFTR Article 15 reuse rules, and determine HQLA impact.
Open ToolValidate issuance, corporate actions, and maturity/redemption lifecycle for tokenized securities on Daml/Canton against required lifecycle events by security type.
Open ToolCompute repo haircut, initial margin, and variation margin, and compare atomic on-chain valuation against a legacy weekend gap, under Basel CRE22, GMRA, and SFTR.
Open ToolTools that check the signature, mandate, or credential behind a token-adjacent action before an agent, wallet, or protocol acts on it.
Build and validate Google's Agent Payments Protocol Checkout Mandate and Payment Mandate verifiable digital credentials. Distinct from the AINumbers Policy Mandate export.
Open ToolDecode and validate RFC 9421 HTTP message signatures, lint a Web Bot Auth JWKS directory, and score readiness against the shared signature substrate under Visa's Trusted Agent Protocol.
Open ToolAudit an MCP server's OAuth 2.1 authorization: validate the RFC 9728 protected-resource-metadata document, check RFC 8707 audience binding, and self-assess for token passthrough and confused-deputy risk.
Open ToolRecompute an ACDC (vLEI credential) self-addressing identifier and cross-check the schema SAID against a pinned GLEIF vLEI schema table. Structural check only, not a KERI trust-chain verifier.
Open ToolAuthor a C2PA manifest definition: actions assertions, ingredient hashes, and a draft CAWG identity block. Composes and verifies structure only, does not sign.
Open ToolRecompute the EIP-712 typed-data digest for an ERC-2612 Permit struct (the gasless-approval rail used by USDC and other ERC-2612 tokens), recover the ECDSA signer, and report whether it binds to the caller-claimed owner. DAI's legacy permit is a different struct this tool does not verify. Makes no claim about on-chain nonce freshness or deadline expiry.
Recompute the Permit2 typed-data digest a payer signs for an x402 payment, across the witness transfer, signature transfer, and allowance permit shapes, deriving each type hash from its type string at run time. Reports the binding facts against a declared payment requirement, the nonce space, the allowance expiry rule, and the signature form, then hands the digest off for signer recovery. Reads no chain and recovers no signer itself.
Read an authorization payload before it is signed and report how it stands against a signing policy you declare. Classifies EIP-712 typed data by encodeType string equality across ERC-2612, the older DAI permit, five Permit2 structs, the three EIP-3009 authorizations, the EntryPoint v0.8 user operation and the OpenZeppelin forwarder request; reads EIP-7702 delegation tuples; flags a bare hash as a blind signing request. Every check returns FLAGGED, CLEAR or NOT_EVALUATED, and a check whose policy input you did not declare is listed as not evaluated rather than counted clear.
Tools for the transfer, metadata, and royalty side of ERC-721/ERC-1155 tokens: validating what gets minted, computing the content identifier that backs a tokenURI, and picking or checking the licensing and royalty-split terms attached to it.
Validate ERC-721/ERC-1155 plus OpenSea metadata JSON against required fields, recommended fields, attributes array structure, and license field presence.
Open ToolCompute a CIDv1 (SHA-256 multihash, raw or dag-pb codec, base32 multibase) for any file or text in your browser. Verify a tokenURI before mint, no pinning, no network.
Open ToolValidate a royalty-split config (ERC-2981 / 0xSplits) against share-sum, per-recipient cap, address format, and duplication rules.
Open ToolGenerate a human-readable TASL attribution line plus machine-readable ccREL JSON-LD and RDFa blocks for a Creative Commons licensed work.
Open ToolPick one of a16z's six Can't Be Evil NFT licenses from rights answers, returning the license id, on-chain enum names, Solidity enum ordinal, and canonical license URIs.
Open ToolMap creator answers to a Story Protocol Programmable IP License flavor and emit the full PILTerms struct.
Open ToolMap two questions, commercial use and adaptations allowed, to the correct Creative Commons license with SPDX id and attribution requirement.
Open ToolTools that decide what a token legally is and what has to be reported about it: securities/commodity/e-money classification, MiCA and GENIUS Act obligations, ERC-3643/ERC-1400 permissioned-token checks, and the permissioned-chain configuration audits token compliance programmes lean on.
Static analysis of ERC-3643 (T-REX) and ERC-1400 token contract metadata: identity registry, compliance contract, claim topics, forced transfer, recovery address, and a jurisdictional compliance matrix.

Open ToolClassify a tokenized asset under the GENIUS Act, MiCA, MiFID II, and the EU DLT Pilot Regime, and determine which framework applies and what falls outside scope.
Open ToolClassify cryptographic assets by algorithm, key size, and use case as quantum-safe, deprecated, or disallowed per NISTIR 8547, and flag harvest-now-decrypt-later risk.
Open ToolTests whether an ART or EMT crosses significant-token criteria under MiCA Articles 43/56, triggering EBA/ESMA dual oversight, across all seven criteria.
Open ToolSchedules and scopes ongoing MiCA reporting obligations by entity and token class, with a full annual calendar of deadlines for NCAs, EBA, and ESMA.

Open ToolVisualize Hyperledger Fabric private-data-collection topology and Canton sub-transaction privacy models, producing a color-coded visibility heatmap by party.
Open ToolScreens a tokenized-asset target's holdings and contract metadata for the classification, custody, and transfer-restriction issues an M&A due diligence review needs to flag.
Open ToolEvery EVM-standard tool above works with any EVM-compatible chain. Worked examples across the suite use Base, BSC, Polygon, Arbitrum, Optimism, and Avalanche C-Chain, but nothing here is chain-specific. There is no chain selector and no per-chain variant: you paste the values from whichever chain you're on.
Solana is covered by a narrower set of notes than EVM. The Solana Foundation DvP program settles a bilateral swap through a third-party settlement authority and takes no part in eligibility, which comes from the mints' Token-2022 controls (program docs, 2026-10-16). It rejects mints that carry a transfer fee, interest-bearing, scaled-UI-amount or non-transferable extension (source @df9919ed). It states that on-chain finalization is not legal finality, which stays contractual. See the Solana DvP note in the Wholesale Tokenized Settlement Fit Diagnostic.
