What to know about Gram (Toncoin) and USD Coin

Gram (Toncoin) (GRAM)

Gram (formerly Toncoin, TON) is the native coin of The Open Network, a blockchain originally designed by the Telegram team. After Telegram stepped away from the project in 2020, development was continued by the community and the TON Foundation.

Sending and receiving GRAM

TON addresses come in two formats (starting with UQ or EQ) that point to the same account. Exchanges usually require a comment (memo) with deposits — without it the funds may not be credited. Transfers take a few seconds.

USD Coin (USDC)

USD Coin (USDC) is a dollar stablecoin issued by Circle since 2018. Each token is backed by reserves held in cash and short-term US Treasuries, and the reserve composition is regularly reported by the issuer.

How USD Coin works

Like USDT, USDC exists on many blockchains — Ethereum, Solana, Polygon, Arbitrum, BNB Smart Chain and others. Circle mints and burns tokens as dollars enter or leave its reserves, which keeps the price close to one dollar.

Optimism network

Optimism is an Ethereum layer-2 network. Addresses use the Ethereum format and fees are paid in ETH at a fraction of mainnet cost.
