Retro Bridge

RetroBridge (the crypto bridge, not the UK modular bridge supplier of the same name) was a multichain bridge and swap app. It ran from 2023 until 28 November 2025, when the team announced on X that it was "officially closing the RetroBridge chapter". It moved assets across more than 53 EVM and non-EVM networks, including Solana, Bitcoin, TON, Sui and Tron, and charged a flat fee per transfer.

It is inactive. The team said demand for bridging across many chains had "dropped hard". Users had settled on a few big chains such as Ethereum, Solana, BSC and Base. The Retro Points program never turned into a token. As of October 2026 the retrobridge.io homepage still loads, but the docs site no longer resolves. The X account has posted nothing since the farewell.

Is RetroBridge shut down?

Yes. The farewell post of 28 November 2025 ended bridging operations. The team called it "a break, a reset" for the group behind it, not a final goodbye, and promised that active community members "will not be forgotten" if it returns with a new product. As of October 2026 it has announced no new product.

The post gave final figures for the bridge's lifetime:

• 53+ supported EVM and non-EVM networks
• almost 3 million transactions
• more than $300 million in volume
• over 50,000 active users at its peak

A case study by Cowchain, the development studio run by co-founder Mykhailo Adzhoiev, gives different totals: $600 million in volume and over 1 million bridges. The farewell post is the later, official figure.

The team said the website and X account would stay up for future updates. The homepage at retrobridge.io still loads with its "All chains, single app" title, but docs.retrobridge.io no longer resolves. Treat the app as closed: do not send funds to any address that claims to be RetroBridge.

How RetroBridge worked

Most bridges lock tokens in a smart contract on one chain. They then release or mint them on the other. RetroBridge held concentrated liquidity pools in dedicated address storages on each chain and paid out with ordinary transfers, so contract logic did not have to run on both sides. The team pitched this as cheaper and faster than contract-based bridging, with most transfers taking around a minute.

In practice, a user sent tokens to RetroBridge's address on the source chain. The service then sent the same asset from its own pool address on the destination chain. That makes it a liquidity-network bridge run by an operator: the user was trusting the team's wallets and payout system, not a set of on-chain contracts anyone could check.

The fee was flat rather than a percentage. A December 2024 Bitrue explainer put it at $1.99 per bridge transaction. That suited mid-sized transfers, where a fixed $2 is cheaper than a percentage fee.

RetroBridge on Solana

Solana was one of the non-EVM chains RetroBridge served, with Bitcoin, Sui, TRON and TON. Users could move SOL and stablecoins between Solana and EVM chains in one app. In the team's weekly route reports for October and November 2025, Solana was often a top source chain. The address on our listing is an EVM address, not a Solana program. So there is no Solana upgrade authority to check.

RetroBridge Advanced Mode, faucet and other tools

RetroBridge also built a few side tools. They are listed in Cowchain's case study and in The Grid's profile:

• Advanced Mode: send from one source network to several destination networks in one go, either all at once (Fast Mode) or at timed intervals (Sequence Mode).
• DEX swaps: in-app token swaps across supported chains.
• Testnet bridge and multichain faucet: each successful mainnet bridge earned faucet tokens, which users could spend on testnet assets for many networks.
• dApp explorer and transaction explorer: a directory of apps you could filter by chain and category, plus a tracker for bridge history and status.
• API and SDK: tools for other apps to plug RetroBridge routes into their own products.

None of these products are running now that the bridge has closed.

RetroBridge airdrop: Retro Points and phase NFTs

Most search interest in RetroBridge came from airdrop farming. Users earned Retro Points from bridge transactions, daily mini-games and social tasks, with multipliers on top, plus retroactive points for past bridges, per Bitrue. Points were billed as the basis for a future RETRO token.

Alongside points, the team ran a four-phase NFT campaign: Sunrise, Midday, Sunset and Midnight. Its soulbound NFTs gave holders a 30% discount on bridging fees.

No RETRO token launched before the shutdown. The farewell post said sorry "for anyone whose expectations didn't play out" and made no promise of a token, a points conversion or a claim. Airdrop trackers now list the campaign as closed. There is nothing to claim. Any site offering a RetroBridge token or points claim should be treated as a phishing attempt.

Who RetroBridge was for

RetroBridge suited people moving small or mid-sized sums between many chains. It was most useful for less common L2s and non-EVM chains that bigger bridges skipped. Airdrop farmers who wanted cheap activity on lots of chains were its other main users. The flat fee and wide reach were the draw.

It was a weaker fit for large sums. Those relied fully on the team's own funds and payout system. There were no on-chain contract guarantees, and we found no published audit.

It now suits nobody as a live service. Anyone who needs to bridge to or from Solana today should use an active bridge (see alternatives below).

Is RetroBridge safe? Risks and custody

• Closed service: the app no longer works, so the main risk now is impersonation. Look-alike domains and fake "claim" pages are common after shutdowns like this.
• Operator custody: transfers ran through team-controlled pool addresses, not verifiable bridge contracts. Users trusted the operator to pay out on the destination chain.
• No public audit found: we found no published security audit of RetroBridge's payout system in its docs or in independent coverage.
• No incidents found: we found no reported exploit or loss of user funds during its run.
• Unmet expectations: the points program ended without a token, a loss of time (and fees spent farming) for users who bridged to earn points.

RetroBridge alternatives for bridging to Solana

Live options for moving assets to and from Solana include deBridge, Wormhole-based apps such as Portal, Allbridge and Mayan. For native USDC, Circle's own bridge added Solana in October 2026 and links it to 18 other chains. The trade-off is reach. Most live bridges cover fewer niche chains than RetroBridge did. But they publish their contracts and security models, so you can check them.

RetroBridge team and history

RetroBridge was founded in 2023, per its LinkedIn page, with a team of 2-10 people. LinkedIn lists Davyd Koriahin as CEO and Mykhailo Adzhoiev as co-founder. Adzhoiev's studio, Cowchain, built the website, the app and supporting infrastructure.

Key dates:

• 2023: RetroBridge launched as a low-fee bridge across major L1 and L2 chains.
• 2024: it added non-EVM chains, including Solana, Bitcoin, TON, Sui and TRON. It also ran the Retro Points and NFT phase campaigns ahead of a planned token launch.
• October 2025: the team was still posting weekly route reports and teasing Monad support.
• 28 November 2025: it announced the shutdown. No RETRO token was ever issued.
