# Information available Onchain

Please find below an exhaustive list of the information available on the blockchain when creating a token or an [ONCHAINID](https://www.onchainid.com/).

#### **Token smart contract**

-   Token name
-   Token symbol
-   Decimals
-   Balance per wallet
-   Wallet addresses that gave allowance to the smart contract
-   Total supply
-   Token ONCHAINID address.
-   Version of the ERC-3643 deployed (currently the V3 is being deployed, it will be replaced by V4 in the coming weeks)
-   Addresses where all tokens are frozen
-   Addresses where only part of the tokens are freezes
-   Status of the token ("on pause" or "unpause")
-   Identity registry smart contract address
-   Compliance smart contract address
-   Wallet address having the ownership on the token smart contractWallet addresses belonging to agents

**Identity registry smart contract**

-   Address of the claim topic registry smart contract.
-   Address of the trusted issuer registry smart contract.
-   Address of the identity registry storage smart contract.
-   Wallet address having the ownership on the identity registry smart contract.

**Identity registry storage smart contract**

-   Addresses of all the identity registry smart contracts using this specific identity registry storage.
-   Wallet address having the ownership on the identity registry storage smart contract (currently Tokeny for the tokens you deploy).

**Claim topics registry smart contract**

-   All the needed claim topic registry (e.g. KYC claim for the tokens you deployed).
-   Wallet address having the ownership on the claim topics registry smart contract.

**Trusted issuer registry smart contract**

-   Wallet addresses of all the authorized claim issuer.
-   For each wallet addresses belonging to an authorized claim issuer, you can also get the list of claims they are authorized to issue.
-   You can make it work the other way around and get all the trusted claim issuers wallet addresses for a specific claim.
-   Wallet address having the ownership on the trusted issuer registry smart contract.

**Compliance smart contracts**

-   Address of the token smart contract linked to the compliance smart contracts.
-   All addresses of compliance smart contracts linked to the token root compliance smart contracts.
-   Mapping to know if a specific module smart contract is linked to the token root compliance smart contracts.
-   Note that depending on your specific compliance rules other data might need to be on-chain.

**ONCHAINID smart contract**

-   Nonce used by the execute/approve function.
-   The hash of the wallet address linked to the ONCHAINID.
-   The wallet address corresponding to a specific key.
-   The purpose and type corresponding to a specific key.

Note that regarding the type, at Tokeny we only use ECDSA and for the purpose there are 3 options (1=management; 2=action; 3=claim).

It can also work the other way around, if you give the purpose, you can get all the keys corresponding to a specific purpose- Payload of the transactions (all the needed data linked to a transaction).

For each claimID you get the hashes for the wallet addresses of the claim issuer and claim topic.
