Program and Vault Addresses

Velocity is two deployed Solana programs: the exchange program, which owns markets, user accounts, orders, and the insurance fund, and the vaults program, which owns delegated trading pools built on top of it. This page is the reference for their addresses and for the other program IDs an integration has to point at.

Deployed programs

The Velocity program ID is the same string on devnet and on mainnet-beta. The SDK still keeps two named constants, VELOCITY_PROGRAM_ID and VELOCITY_DEVNET_PROGRAM_ID, so that they can diverge without a code change; do not collapse them in a client config. What differs between the two environments is state, not the program ID: separate State accounts, separate markets, and a different quote mint (USDT on mainnet-beta, dUSDT on devnet).

Supporting program IDs

An integration usually needs three more addresses, all of which the SDK carries so none of them has to be pasted by hand:

Read them from the config, not from this page

getConfig() returns the active environment's VelocityConfig, which carries every address above plus the quote mint and the market lookup tables. Reading from it means an address change reaches an integration through an SDK bump rather than through a find-and-replace:

import { initialize, getConfig } from "@velocity-exchange/sdk";

initialize({ env: "mainnet-beta" });
const config = getConfig();

config.VELOCITY_PROGRAM_ID;   // vELoC1audYbSYVRXn1vPaV8Axoa9oU6BYmNGZZBDZ1P
config.QUOTE_MINT_ADDRESS;    // USDT on mainnet-beta, dUSDT on devnet
config.MARKET_LOOKUP_TABLES;  // address lookup tables for versioned transactions

initialize() mutates process-wide module state, so call it once at startup. Without it the SDK defaults to the devnet preset, which is a common cause of a mainnet integration deriving devnet addresses. See Setup for the rest of the client bootstrap.

Every PDA is derived against the program ID

No account address on Velocity is a constant that can be hardcoded. State, user accounts, markets, market vaults, and insurance fund vaults are all program-derived addresses, so each one is a function of the program ID above and its seeds. The seed list is in Account Model, and the SDK derives them offchain with getUserAccountPublicKey(), getPerpMarketPublicKey(), and getSpotMarketPublicKey().
