COTI is the fastest, lightest privacy layer in Web3, powered by the breakthrough cryptographic protocol Garbled Circuits. Build with privacy. Scale with speed.
COTI Testnet is a public sandbox for the COTI network’s DAG-based Trustchain, where developers use test COTI to build and validate wallets, cross-chain bridge flows, payment rails, and compliance-aware privacy features before mainnet deployment. It enables end-to-end testing of high-throughput payments, merchant settlement, and treasury operations without real funds.
COTI Testnet is unique because it runs on a DAG (no fixed blocks), enabling parallel transaction confirmation, low fees in COTI (not EVM gas), and privacy/compliance primitives tailored for payments. For comparison metrics as of Sep 2025: block speed — not applicable (DAG with near real-time confirmations), average gas/fee — negligible on testnet via faucets, TPS — elastic and workload-dependent rather than fixed, activity — intermittent; check the current testnet explorer for live figures.
COTI Testnet uses COTI as the gas token for transaction fees. You can obtain COTI by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge COTI to COTI Testnet, connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select COTI Testnet as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on COTI Testnet you can use thirdweb, which provides an easy way to build, monetize and scale your apps, games or agents. You can find detailed guides and documentation on https://portal.thirdweb.com to get started quickly.
To add COTI Testnet to your wallet, you can connect your wallet and click on [Add to Wallet] button at the top of the page. Alternatively, you can add the network manually using the RPC URL and chain details and add it to your wallet's network settings.
To send COTI on COTI Testnet, ensure your wallet is connected to the COTI Testnet network, enter the recipient's address, specify the amount of COTI to send, review the gas fee, and confirm the transaction in your wallet.
