EVM Blockchain Bridge

A whitelabel cross-chain bridge enabling seamless asset transfers between EVM-compatible blockchains. The system uses Solidity smart contracts deployed on each supported network with role-based access control (minter, burner, admin) and configurable token support. A Python-based centralized event watcher monitors deposit events across all chains, verifies transactions, and issues cryptographically signed redemption tickets. Users deposit on the source chain, receive a signed ticket, then claim tokens on the destination chain — with the contract verifying the signature before minting or transferring.

The Challenge

Blockchain projects needed a reliable, auditable bridge to move assets between EVM networks without relying on third-party bridge protocols. The solution required on-chain signature verification, role-based contract administration, real-time cross-chain event monitoring, and a trustless redemption flow — all deployable as a whitelabel product.

Our Approach

We built a complete bridge system: Solidity smart contracts with role-based access (minter/burner/admin), configurable token whitelisting per chain, a Python-based centralized event watcher monitoring deposits across all supported networks, cryptographic ticket signing for cross-chain redemption, and a frontend that guides users through the deposit → ticket → claim flow. Each deployment gets its own branding and supported network configuration.
