Infrastructure Addresses

Public registry of infrastructure wallets and smart contracts across supported blockchains.

Address Roles

Treasury

The Treasury wallet stores operational liquidity used for payouts and service execution. This address typically holds the primary balances used by the platform.

Executor

The Executor wallet is an infrastructure wallet responsible for submitting transactions to blockchain networks. Executor wallets typically:

  • Pay network transaction fees
  • Submit batched operations
  • Interact with infrastructure smart contracts

Batcher Smart Contract

The Batcher smart contract is a custom multi-call contract that enables infrastructure to execute multiple operations within a single blockchain transaction:

  • Batch token operations
  • Reduce gas costs
  • Execute meta-transaction based flows
  • Process multiple user operations atomically

EVM-Compatible Networks

The following addresses apply to the mainnets of: Ethereum, Polygon, Arbitrum, Base, Optimism, Celo, BNB Smart Chain (BSC), and Avalanche.

Solana Network

Solana infrastructure differs from EVM networks because transactions are composed of multiple signed instructions.

  • The Treasury wallet stores token balances (such as USDC and USDT)
  • The Executor wallet holds SOL used for paying network fees

Transactions are executed by the Executor while interacting with Treasury-owned token accounts.

There is no dedicated smart contract on Solana for batching, as multi-instruction transactions are supported natively by the Solana runtime.

Additional Notes

The infrastructure manages a large number of user-specific deposit addresses that are assigned to individual users. These addresses are used solely for receiving deposits and are programmatically processed by the infrastructure. Deposit addresses are not listed here due to their large number and operational rotation. Funds received at deposit addresses are processed through the batching infrastructure and consolidated into operational wallets listed above.
