Asset

An asset refers to a specific cryptocurrency or blockchain-based token supported in our crypto custody platform.

We support native tokens on major blockchains like Bitcoin, Ethereum and much more. We also support common ERC-20 tokens on the Ethereum blockchain and other standards on additional chains.

The assets you activate in the platform represent the cryptocurrencies and tokens your customers will transact and you wish to custody. An asset must be officially listed as supported by our platform before it can be added. Please contact us if there are additional assets you require for your cryptocurrency operations.

ON1ON Custody will always represent the assets in the following format:

{
    "chain": "CHAIN_ETHEREUM",
    "contract": "0x9e07842eCd4485cD59d448284653DC354440859A",
    "contract_standard": "ERC-20",
    "name": "Reaching Your Apex 4",
    "symbol": "RYA4",
    "icon": "https://s3.ap-east-1.amazonaws.com/file.on1on-custody.com/public/icon/eth.png",
    "asset_id": 35,
    "properties": {}
}

You may query the assets available to you by querying the API here.

An asset can be defined in two ways, for everywhere that you need to provide an asset as parameter:

Native Blockchain Way

{
    "chain": "CHAIN_ETHEREUM",
    "contract": "0x9e07842eCd4485cD59d448284653DC354440859A",
}

Asset Identifier Way

{
    "asset_id": 35,
}

Asset identifiers (asset_id) are permanently mapped to the same asset in our system and remain constant over time. Therefore, it is safe for you to persistently store an asset_id in your own database and records to reference the associated asset.
