Solana Go Tools

Solana Go cli tools we used in early development while building magic.markets to create and manage a stable coin mint substitute on local and devnet. Such mint is used by our escrow program and is the medium of exchange for market participants. This heavily depends on the fantastic Go package gagliardetto/solana-go.

Custom rpc and websocket URLs are supported as well as monikers (and by their first letter), mainnet-beta, testnet, devnet, localhost.

Create a new token keypair using the solana toolchain:

solana-keygen new --outfile mytoken.json

Create the mint using the keypair on devnet:

go run create_escrow_mint/main.go -decimals 6 -payer ~/.config/solana/id.json -mint mytoken.json -url devnet

Mint 100k tokens to acccount <PUBKEY> on devnet:

go run mint_escrow_tokens/main.go -amount 100000 -mint mytoken.json -payer ~/.config/solana/id.json -receiver <PUBKEY> -url d
