Question 1

What is GetBlock LandFirst for Solana?

Accepted Answer

LandFirst is GetBlock's intelligent transaction-routing technology achieving 95%+ landing probability through multi-path delivery across owned SWQoS validator connections, leased SWQoS routes, and Jito Block Engine integration. This ensures reliable inclusion even during congestion.

Question 2

How does LandFirst's multi-path routing work?

Accepted Answer

LandFirst analyzes each transaction using leader schedule awareness, Jito tip detection, network conditions, fees, and geographic latency to select optimal paths. It submits transactions in parallel through owned SWQoS validators, leased SWQoS partners, and the Jito Block Engine to maximize fast inclusion.

Question 3

What is Stake-Weighted Quality of Service (SWQoS) and why does it matter?

Accepted Answer

SWQoS allocates validator capacity by stake weight, giving priority to staked connections while unstaked RPC traffic competes for limited bandwidth. GetBlock maintains owned and leased SWQoS links with high-stakes validators, giving LandFirst transactions priority during congestion.

Question 4

How does LandFirst integrate with Jito for MEV protection?

Accepted Answer

LandFirst detects Jito tips and routes such transactions through the Jito Block Engine, participating in off-chain bundle auctions that guarantee ordering, protect against MEV attacks, and improve priority inclusion when competitive tips are provided.

Question 5

What applications benefit most from LandFirst?

Accepted Answer

DeFi protocols, trading bots, arbitrage systems, NFT drops, and dApps requiring reliable execution benefit most. LandFirst ensures consistent landing during volatility, high-competition mints, market-making operations, liquidations, and high-value transfers.

Question 6

What is the difference between LandFirst and standard RPC transaction submission?

Accepted Answer

Standard RPC uses single unstaked connections with lower landing probability and no MEV protection. LandFirst routes through three prioritized paths using SWQoS staking advantages and Jito integration, achieving 95%+ landing probability with adaptive congestion handling.

Question 7

How does LandFirst handle Solana's leader schedule?

Accepted Answer

LandFirst monitors the leader schedule to identify current and upcoming block producers. If GetBlock has SWQoS connections to these validators, routing is prioritized through them to maximize transaction inclusion probability.
