Retro Bridge

RetroBridge was a multichain bridge and asset-transfer platform that operated from 2023 until November 2025, when it shut down citing changes in market conditions. At its peak the service supported more than 50 blockchain networks — covering EVM Layer 2s alongside non-EVM chains including Solana, Bitcoin, TON, Sui, Aptos, Cosmos, StarkNet, and Tron — making it one of the broader-coverage bridges of its era.

How It Worked

Rather than routing every transfer through shared smart contracts, RetroBridge held concentrated liquidity pools in dedicated address storages on each supported chain and settled transfers using direct transfer functions. The team described this approach as cheaper and faster than traditional contract-based bridging because it avoided the overhead of executing contract logic on both ends of a cross-chain transaction.

Users interacted through a single web application that presented available routes, fees, and estimated completion times across all connected networks. A fixed fee of roughly $1.99–$2.50 per transaction applied to most transfers, while stablecoin swaps (USDC and USDT across EVM chains) were offered with zero fees as a promotional feature.

An "Advanced Mode" allowed users to broadcast funds from one source address to multiple destination networks in a single workflow, targeting power users and developers managing multi-chain treasury operations.

Ecosystem Features

Beyond the core bridge, RetroBridge built out several adjacent tools:

• DEX integration — in-app token swaps across supported chains
• Testnet bridge and faucet — a staging environment where users could practice transfers without real assets
• dApp explorer — a directory of decentralized applications filterable by chain and category
• SDK and API — business-facing tools for integrating RetroBridge routing into third-party products

The platform also ran a points program ("Retro Points"), credited at a flat rate per bridging or swap transaction, intended to convert into a future RETRO utility token. The token generation event was anticipated throughout 2024 but never delivered in its original form before the project wound down.

Scale and Team

RetroBridge reported processing more than $600 million in bridged transaction volume and over one million completed cross-chain transfers during its operating period. The company was incorporated in Poland and founded by Davyd Koriahin (CEO) and Mykhailo Adzhoiev (Co-Founder). The project raised $500,000 in early funding.

Shutdown

On November 28, 2025, RetroBridge published a farewell message to its community acknowledging that "the space changed" and that it was ending operations. The retrobridge.io domain subsequently lapsed, and the airdrops.io listing confirmed the shutdown with the notation that the project closed due to market conditions. The RETRO airdrop was marked as ended without distribution to participants who had accumulated points.
