Supported assets and networks
cross river support cross river’s crypto payments support usdc transfers across multiple blockchain networks , giving partners flexibility in speed, cost, and performance each supported network is selected and maintained to meet cross river’s standards for reliability, interoperability, and settlement efficiency supported asset usdc a fully reserved u s dollar–denominated stablecoin issued by circle each token represents one u s dollar held in reserve used for sending and receiving digital payments on supported blockchains cross river will expand to additional stablecoins and networks as industry adoption grows supported networks ethereum ethereum is the most widely adopted blockchain for digital asset transfers and tokenized payments it offers extensive interoperability and established developer tools, making it suitable for broad ecosystem compatibility settlement time typically completes within seconds to a few minutes, depending on network congestion transaction fees determined by network gas prices and paid in eth precision unit wei (1 usdc = 1e6 wei) use case focus ideal for high value or enterprise transactions where transparency and ecosystem compatibility are prioritized solana solana is a high throughput, low latency blockchain optimized for efficiency and speed it provides near instant finality and minimal transaction fees, making it well suited for high volume or retail use cases settlement time typically completes within seconds transaction fees extremely low; paid in sol precision unit lamport (1 usdc = 1e6 lamports) use case focus ideal for real time payouts, merchant settlements, or high frequency payment scenarios token denominations each blockchain represents asset values in smaller units to support precise transactions and accurate fee calculation when making api requests, amounts should always be provided in the smallest denomination supported by the selected blockchain usdc ethereum wei 1 usdc = 1,000,000 wei amount = 1000000 represents 1 usdc usdc solana lamport 1 usdc = 1,000,000 lamports amount = 1000000 represents 1 usdc eth ethereum wei 1 eth = 1,000,000,000,000,000,000 wei (1e18) used for network gas fees sol solana lamport 1 sol = 1,000,000,000 lamports (1e9) used for network gas fees use the amount field in your api calls to specify values in the smallest denomination for example, to send 1 usdc, set "amount" 1000000 network selection partners can select a network for each transaction using the blockchain field in the api request cross river manages network interaction, transaction broadcasting, and confirmation tracking automatically example request cur { "accountnumber" "2917000057", "amount" 1000000, "currency" "usdc", "blockchain" "solana", "externaladdressid" "9f9e2c43 8a2d 4cd7 a3f0 b39e012789ab" } payment choose the right network ethereum broad adoption, strong ecosystem support, established compliance tooling enterprise settlements, program level transfers solana low latency, low fees, high transaction throughput merchant payouts, consumer disbursements, high frequency flows
