Paano magpadala ng mga SPL-Token

Gamitin ang Token Program para maglipat ng SPL Token. Para makapagpadala ng SPL token, kailangan mong malaman ang address ng SPL token account nito. Maaari mong parehong kunin ang address at magpadala ng mga token kasama ang sumusunod na halimbawa.

Paano kalkulahin ang gastos sa transaksyon

Ang bilang ng mga lagda na kailangan ng isang transaksyon ay ginagamit upang kalkulahin ang halaga ng transaksyon. Hangga't hindi ka gumagawa ng account, ito ang magiging huling halaga ng transaksyon. Upang malaman ang higit pa tungkol sa mga gastos sa paggawa isang account, tingnan ang calculating rent exemption

Ang dalawang halimbawa sa ibaba ay nagpapakita ng dalawang paraan na kasalukuyang magagamit upang kalkulahin ang tinantyang gastos sa transaksyon.

Ang unang halimbawa ay gumagamit ng getEstimatedFee, na isang bagong paraan sa Transaction na klase, habang ang pangalawang halimbawa ay gumagamit ng getFeeForMessage na pumapalit sa getFeeCalculatorForBlockhash sa Connection na klase.

Paano baguhin ang pagkalkula ng badyet, bayad, & priyoridad para sa isang transaksyon

Ang priyoridad ng Transaction (TX) ay nakakamit sa pamamagitan ng pagbabayad ng Prioritization Fee in karagdagan sa Base Fee. Bilang default, ang compute budget ay produkto ng 200,000 Compute Units (CU) * bilang ng mga instruction, na may max na 1.4M CU. Ang Ang Base Fee ay 5,000 Lamports. Ang isang microLamport ay 0.000001 Lamports.

Ang kabuuang compute budget o Prioritization Fee para sa isang TX ay maaaring baguhin ng pagdaragdag ng mga instruction mula sa ComputeBudgetProgram.

ComputeBudgetProgram.setComputeUnitPrice({ microLamports: number }) ay magdaragdag ng Prioritization Fee sa itaas ng Base Fee (5,000 Lamports). Ang halaga na ibinigay sa microLamports ay pararamihin sa badyet ng CU upang matukoy ang Bayarin sa Prioritization sa Lamports. Halimbawa, kung ang iyong badyet sa CU ay 1M CU, at ikaw magdagdag ng 1 microLamport/CU, ang Prioritization Fee ay magiging 1 Lamport (1M * 0.000001). Ang kabuuang bayad ay magiging 5001 Lamports.

Gamitin ang ComputeBudgetProgram.setComputeUnitLimit({ units: number }) para itakda ang bagong compute budget. Papalitan ng value na ibinigay ang default na value. Ang mga transaksyon ay dapat humiling ng pinakamababang halaga ng CU na kinakailangan para sa execution para ma-maximize ang throughput, o mabawasan ang mga bayarin.
