Circle Gateway Brings Unified EURC Balances to Solana, With 20M EURC in a New Pre-Mint Account

Circle USDC$1.000+0.0% Gateway now offers unified EURC balances on Solana SOL$101.84-2.3%, and the change arrives with a new Solana pre-mint account that, according to Solana Compass token data, holds 20,000,009.79 EURC. That is about 16% of the 125.02 million EURC on the Solana mint. Circle announced the euro stablecoin's arrival on Gateway and the Solana pre-mint address in two blog posts on 23 October 2026.

Solana is one of six EURC chains in the expansion. Circle's Gateway announcement lists Arc, Avalanche, Base, Ethereum, Solana and World Chain for EURC, alongside the existing USDC support. Circle's bitcoin token, cirBTC, was added on Arc and Ethereum only, so it is not part of the Solana rollout.

What Circle Gateway does for EURC on Solana

Circle Gateway lets a business or app hold one balance of a Circle asset and spend it on any supported chain. Per the Gateway documentation, users deposit USDC, EURC or cirBTC into non-custodial Gateway Wallet contracts on a source chain, then mint the same asset on a destination chain with a single API call. Circle says access on the destination chain takes under 500 milliseconds after the deposit finalizes.

Circle's Cross-Chain Transfer Protocol (CCTP) works differently. It moves funds point to point between two chains and takes about 8 to 20 seconds on its fast route, according to the same documentation. Gateway is closer to one bank account usable at branches in several countries, where CCTP is a wire between two accounts.

The Gateway fee for EURC is 1 basis point (0.01%) outside Arc, double the 0.5 basis points charged on USDC, and fees are waived on Arc at launch. Withdrawals are permissionless but carry a 7-day delay, so users can reclaim funds from the contract without relying on Circle's API. Gateway has processed over $10 billion in volume, per the announcement.

How the Solana EURC pre-mint address works

The pre-mint is how Gateway delivers EURC on Solana. Pre-mint addresses hold an existing EURC balance that Circle does not count as in circulation, the Solana post explains. When a Gateway user mints EURC on Solana, the tokens are sent from the pre-mint address (A6sLLUWebvoUUnQoCiB45ktetd34iamfD8kwTsBSReAb) to the user's wallet, which increases EURC in circulation. The same approach was used for USDC on Solana.

The address is for Circle alone, and EURC sent to it is lost:

Exchanges, websites and developers that monitor EURC flows on Solana need no changes, according to Circle, because its public API works as before.

Reading EURC supply on Solana after the pre-mint

The pre-mint changes what the raw supply number on the Solana mint means. Solana Compass data shows total supply on the EURC mint held at about 105.02 million from late July 2026 through the 22 October daily reading, then stood at 125.02 million in the 23 October reading, the date of Circle's posts. The pre-mint account's 20.0 million EURC, worth about $22.4 million at Compass's EURC price on 24 October, matches that step in size and timing, though Circle's posts do not state an amount or a funding date.

For anyone tracking euro stablecoins on Solana, the practical result is that the mint now reports about 20 million more EURC than Circle counts as circulating. Subtracting the pre-mint balance gives roughly 105.0 million, where supply sat before 23 October. Because Gateway mints on Solana move tokens out of an existing account instead of creating them, a Gateway mint on Solana should show up as the pre-mint balance shrinking, without adding to total supply on the mint.

Supply is also concentrated: the largest EURC account on Solana, which Compass labels as a Circle treasury, holds 58.3 million EURC (46.6% of mint supply), per Compass holder data on 24 October.

Where Circle's EURC on Solana stands

Across all chains, Circle posted on X on 23 October that EURC is "the first euro stablecoin to cross €450M in circulation." In September we covered how the euro stablecoin market splits across Ethereum, Solana and Base, with Solana in second place.

On Solana itself, EURC has more than 60,000 holder accounts, per Compass. Some of it sits in DeFi: the Orca ORCA$1.70-7.4% USDC-EURC pool holds about 282,000 EURC and a Jupiter JUP$0.295-5.6% Lend supply vault about 493,000, according to the same holder data. Payments firm Thunes added EURC prefunding on Solana in August for round-the-clock euro settlement.

Gateway follows Circle's USDC Bridge adding Solana on 6 October. For a euro treasury already holding EURC on Ethereum or Base, Gateway makes Solana a chain it can fund from the same balance in under a second, paid out of the pre-mint account's 20 million EURC.
