Paribu Joins Circle's Arc Launch With Day-One USDC Deposits in Turkey

Paribu Becomes Arc's Turkish Launch Partner

Turkish cryptocurrency exchange Paribu has been named among the launch partners for Arc in Turkey — the open Layer-1 blockchain developed by Circle, the issuer of the USDC stablecoin, which went live on its mainnet on Tuesday, September 16. Under the arrangement, Paribu users can deposit and withdraw USDC over Arc starting from the network's very first day of mainnet operation, giving the new chain exchange-side rails in one of Europe's most active retail crypto markets from the outset. Paribu joined the launch as a Day 1 Launch Partner, a designation with a practical consequence: an asset issued on Arc becomes accessible inside Paribu DeFi at the same moment it is reachable anywhere else in the market, rather than days or weeks later once integrations catch up. The exchange has been a fixture of Turkey's blockchain ecosystem since 2017 and has built its brand on bringing global infrastructure to local users. USDC itself is the second-largest stablecoin by market capitalization, so day-one support is a meaningful signal for the network's early liquidity. The commitment extends beyond trading. Paribu Custody, the exchange's subsidiary and the first digital asset custody provider in Turkey to run on fully self-developed technology, also supports Arc from launch day, per the exchange's official announcement. Institutional clients can hold assets on the new network under ColdShield, a security framework combining HSM, MPC and Secure Enclave technologies. The custody unit already supports more than 1,000 tokens across over 90 networks, and Arc now becomes the newest addition to that coverage. Turkish users moving funds through a local, licensed venue therefore gain a native path to the stablecoin's new home chain without ever leaving the platform.

Institutional Validators and Sub-Cent Fees

Arc's technical design explains why Circle recruited exchanges before the mainnet went hot. The network bills itself as the “economic operating system for the internet” — an open, EVM-compatible Layer-1 built for global financial markets, real-time money movement and economic activity executed by AI agents. Its most distinctive choice is gas: transaction fees are paid in USDC by default, meaning a user moving the stablecoin does not need to acquire a second asset just to cover network costs — a long-standing friction in stablecoin settlement on general-purpose chains. EVM compatibility should also keep bridge protocol integration straightforward for developers porting existing contracts. Performance figures come from the issuer itself: across testnet work involving more than 100 ecosystem and institutional developers, focused on stablecoin payments, tokenized asset issuance, foreign exchange and institutional on-chain markets, average transaction costs stayed below $0.01, according to Circle's published data. Network security rests on a validator roster of financial institutions across multiple geographies — a lineup that includes BlackRock, which also runs the world's largest spot Bitcoin ETF, alongside Mastercard, Visa, Intercontinental Exchange and Standard Chartered. In contrast to the open staking participation typical of public chains, Arc anchors security with named institutional validators. At launch, the chain activated lending and borrowing, on-chain foreign exchange, payments and tokenized asset market capabilities, with a roadmap stretching beyond stablecoin transfers to local-currency stablecoins, tokenized real-world assets and programmable Bitcoin. The geography matters too: Paribu operates CoinMENA across the Middle East and North Africa, so one integration gives Arc distribution into both Turkey and MENA — corridors where stablecoin usage for payments and savings is already substantial.

What the Turkey Entry Signals

In COINOTAG's reading, Arc's launch marks a shift in how new Layer-1 networks enter the market: rather than courting retail speculation first, as general-purpose chains such as the NEAR Protocol did, Circle assembled regulated institutions and licensed exchange partners before the first block was even produced. Day-one custody and day-one deposit rails matter more for early liquidity than incentive programs, and Paribu's dual role — exchange and institutional custodian — gives Arc both in a single market. What remains undisclosed is just as notable: Paribu has not published Arc-specific fee schedules, nor confirmed a timeline for lira-denominated stablecoin functionality on the network. Readers should treat both as unconfirmed until the exchange issues further details.
