Token Standards Library
The right contract standard for every asset, account and credential.
What it does
Not every asset, account or credential belongs in the same kind of contract. The Token Standards Library holds audited, ready-to-deploy implementations of the standards the ecosystem uses: ERC-3643 for regulated security tokens, ERC-20 for fungible tokens such as stablecoins and $SBX, ERC-1155 for fractional units issued in series, ERC-721 and ERC-5192 for unique and soulbound tokens, ERC-4626 for pooled vaults, and ERC-4337 with ERC-7579 for smart accounts. The Module Composer picks the standard that fits each product, so teams never rebuild or re-audit the basics.
How it works
The library sits beneath the Tokenisation Engine and Smart Accounts. The Module Composer draws on it whenever a product is assembled, and the Security & Audit Layer keeps every implementation in it reviewed.

Step 1 of 3: Describe. A product sets out what it needs: regulated shares, a stablecoin, a credential or a savings pool.
Key capabilities
Security tokens
ERC-3643 with ONCHAINID investor identities, so eligibility is enforced by the token.
Fungible and multi-token
ERC-20 for stablecoins and utility tokens, ERC-1155 for fractional units issued in series.
Soulbound and unique tokens
ERC-5192 for non-transferable credentials, ERC-721 for one-of-a-kind assets.
Vaults and smart accounts
ERC-4626 pooled vaults and ERC-4337 accounts with ERC-7579 modules, on the same audited base.
