TAC (SPB) is a testnet network with native TAC used by the cross-chain bridge to validate transfers, smart-contract calls, and wallet flows before mainnet deployment. TAC is faucet-distributed and has no monetary value, enabling risk-free simulations of swaps, liquidity operations, and cross-chain messages. As of 2025-09-24, no official public metrics are published for average gas cost, block speed, TPS, or network activity; in practice, gas is near-zero and blocks confirm quickly as is typical for testnets.
TAC (SPB) is purpose-built for bridge integration, prioritizing low fees, rapid confirmations, and safe, repeatable end-to-end testing over economic security. Unlike production networks, it may be reset and experiences bursty activity during coordinated test campaigns, so average gas cost is effectively negligible while TPS and block speed reflect test conditions rather than steady-state throughput. This developer-focused design differentiates it from general-purpose public networks and makes it a reliable staging ground for cross-chain QA.
TAC (SPB) uses TAC as the gas token for transaction fees. You can obtain TAC by bridging from other chains or purchasing using thirdweb Bridge, or through faucets (for testnet).
To bridge TAC to TAC (SPB), connect your wallet to thirdweb bridge, select your source chain, choose the token you want to bridge, select TAC (SPB) as the destination, enter the amount, and confirm the transaction. The bridge will handle the cross-chain transfer instantly.
To build on TAC (SPB) 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 TAC (SPB) 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 TAC on TAC (SPB), ensure your wallet is connected to the TAC (SPB) network, enter the recipient's address, specify the amount of TAC to send, review the gas fee, and confirm the transaction in your wallet.
