Como enviar Tokens SPL

Use o Programa de Tokens para transferir tokens SPL. Para enviar um token SPL, você precisa saber o endereço da conta do token SPL. Você pode obter o endereço e enviar tokens como no exemplo a seguir.

Como calcular o custo da transação

O número de assinaturas que uma transação requer é usado para calcular o custo da transação. Contanto que você não esteja criando uma conta, este será o custo final da transação. Para saber mais sobre os custos para criar uma conta, confira o cálculo da isenção de aluguel.

Os dois exemplos abaixo mostram as duas maneiras atualmente disponíveis de calcular o custo estimado da transação.

O primeiro exemplo usa o getEstimatedFee, que é um novo método na classe Transaction, enquanto o segundo exemplo usa o getFeeForMessage, que substitui o getFeeCalculatorForBlockhash na classe Connection.

Como adicionar uma observação em uma transação

Uma mensagem pode ser adicionada a qualquer transação usando um programa de mensagens chamado Programa Memo. Atualmente, o programID do Programa Memo tem que ser adicionado manualmente - MemoSq4gqABAXKb96qnH8TysNcWxMyWCqXgDLGmfcHr.

Como alterar o orçamento de computação, taxa e prioridade para uma transação

A prioridade da transação é alcançada pagando uma taxa de priorização além da taxa base. Por padrão, o orçamento de computação é o produto de 200.000 unidades de computação (UC) * número de instruções, com um máximo de 1,4M UC. A taxa base é de 5.000 Lamports. Um microLamport é igual a 0,000001 Lamports.

O orçamento total de computação ou a taxa de priorização para uma única transação podem ser alterados adicionando instruções do ComputeBudgetProgram.

ComputeBudgetProgram.setComputeUnitPrice({ microLamports: number }) irá adicionar uma taxa de priorização acima da taxa base (5.000 Lamports). O valor fornecido em microLamports será multiplicado pelo orçamento de UC para determinar a taxa de priorização em Lamports. Por exemplo, se o seu orçamento de UC for de 1M UC e você adicionar 1 microLamport/UC, a taxa de priorização será de 1 Lamport (1M * 0,000001). A taxa total será então de 5001 Lamports.

Use ComputeBudgetProgram.setComputeUnitLimit({ units: number }) para definir o novo orçamento de computação. O valor fornecido substituirá o valor padrão. As transações devem solicitar a quantidade mínima de UC necessária para a execução a fim de maximizar o throughput ou minimizar as taxas.
