object

Solana 区块链上不同优先级的详细费用估算（单位：microlamports），允许开发者选择成本与确认速度之间的最佳平衡。

显示子属性

result.priorityFeeLevels.min

number<float>

Solana 交易的最低可行费用 - 适用于低拥堵期间的非紧急交易（在网络拥堵期间可能导致交易失败）

result.priorityFeeLevels.low

number<float>

Solana 交易的低优先级费用 - 对于不时间敏感的交易来说是经济的选择（确认时间较长，成本较低）

result.priorityFeeLevels.medium

number<float>

Medium priority fee for Solana transactions - balanced option for most standard transactions (reasonable confirmation time with moderate cost)

result.priorityFeeLevels.high

number<float>

High priority fee for Solana transactions - prioritized processing for time-sensitive operations like DeFi trades or NFT mints (faster confirmation, higher cost)

result.priorityFeeLevels.veryHigh

number<float>

Very high priority fee for Solana transactions - premium option for critical transactions requiring near-immediate confirmation (very fast confirmation, premium cost)

result.priorityFeeLevels.unsafeMax

number<float>

Maximum observed fee on Solana - the highest fee seen in the analysis window, representing an upper bound during extreme congestion (fastest possible confirmation, but potentially unnecessarily high)
