Solflare Bridge Brings Bitcoin and Ethereum Transfers to Solana

Solflare has launched a cross-chain deposit service that allows users to fund its self-custodial Solana wallet directly from Bitcoin, Ethereum, and several other major networks.

Called Bridge, the feature is powered by Aurora Intents, a cross-chain execution system developed by Aurora Labs on top of NEAR Intents. It is available through Solflare’s mobile app, web platform, and browser extension.

Instead of sending users to an external bridge, the service creates permanent deposit addresses for supported network-and-token combinations. Users send assets to an address as they would when funding a centralized exchange, while Aurora Intents handles routing, liquidity, and conversion in the background.

Transfers from Ethereum-compatible networks typically settle in under one minute, while Bitcoin deposits take approximately 14 minutes, according to Aurora Labs.

Solflare Turns Cross-Chain Bridging Into a Deposit

Moving assets between blockchains ordinarily requires users to visit a third-party decentralized application, connect a wallet, approve several transactions, and manage gas or routing complications.

Solflare Bridge reduces that process to a transfer. Each supported source-chain-and-token pair receives a reusable deposit address, removing the need to connect a wallet to an unfamiliar application.

“The wallet connection scares people far more than the number of steps does,” Aurora Labs CEO Declan Hannon said. “Exchanges trained users to copy a deposit address and send funds, and Aurora Intents now brings that same action to a self-custodial wallet.”

Bitcoin, Ethereum, Arbitrum, BNB Chain, Polygon, Tron, NEAR, and Base are supported at launch. Users can deposit major tokens, subject to liquidity, and generally receive SOL or stablecoins on Solana.

“Apps lose users at the funding step, and most of those users already hold assets somewhere else,” Hannon added. “Aurora Intents turns that into a deposit address, and both the funds and the users arrive on Solana.”

How Aurora Intents Protects Cross-Chain Transfers

Aurora Labs Head of Product Armand Didier told CCN that each user request contains binding execution conditions, including a minimum output, maximum fee and deadline.

“The intent carries minAmountOut, maximum fee and deadline,” Didier said. “A solver cannot settle for less than the committed output. A bad route means the fill does not happen, not that the user eats the difference.”

Multiple solvers compete to execute the same request, preventing a single provider from determining the route unilaterally.

“Route quality is a market outcome, not one party’s discretion,” Didier explained. “Multiple solvers bid on the same intent.”

Settlement occurs through the NEAR Intents contract rather than a conventional lock-and-mint bridge. According to Didier, this design avoids the trust assumptions associated with traditional bridges.

“There is no bridge trust assumption,” he said. “Settlement runs through the NEAR Intents contract, not a lock-and-mint bridge.”

NEAR Intents has processed more than $23 billion since launching and now handles over $2.3 billion in monthly volume.

Fees, Slippage and Solana’s Expansion

Solflare charges 0.1% for stablecoin-to-stablecoin deposits and 1% for other transfers, based on the tokens received. Deposits will be free for the first 30 days, subject to an aggregate ceiling of $125,000 in waived fees.

Didier stressed that Solflare, rather than Aurora Labs, determines these customer-facing charges.

“That’s actually Solflare’s call, not ours,” he said. “Aurora Intents is the execution layer underneath, we don’t set the fee end users see, our partners do.”

He added that Aurora’s role is to provide certainty over the amount delivered.

“What Aurora Intents controls is the execution guarantee underneath whatever fee a partner sets,” Didier said. “A solver commits to a minimum output before the trade fills, so there’s no slippage surprise.”

That differs from route-selection bridges, where users set a tolerance and may receive a worse rate within that range.

“That guarantee holds regardless of what a given partner charges on top,” Didier added.

The launch comes as Solana’s monthly active addresses reportedly increased by approximately 50% during the first quarter of 2026.

By making cross-chain deposits resemble familiar exchange transfers, Solflare and Aurora Labs aim to convert users holding assets elsewhere into active Solana participants.
