Guaranteed Blockspace is a dedicated blockspace-allocation model that reserves a fixed share of every block’s capacity for enrolled enterprise partners, regardless of broader network conditions. Transactions routed through the guaranteed path execute with predictable latency and cost. Payroll, settlement, and supplier payments don’t compete with public mempool traffic.
Planned. Guaranteed Blockspace is a forward-looking roadmap item. See Roadmap for timing.

Why this matters

General-purpose chains weren’t designed for fee predictability under load:
  • Ethereum: on May 1, 2022, the Yuga Labs “Otherside” NFT mint pushed peak gas above 8,000 gwei and burned over $200M in fees, breaking any workload that required deterministic cost.
  • Low-fee networks like Solana and Base attract MEV and arbitrage spam, so legitimate transactions compete with bot traffic for inclusion.

Enterprise payment flows can’t tolerate this variance. Guaranteed Blockspace addresses it directly.

​
How the guarantee works

The guarantee is enforced at three layers:
  • Guaranteed mempool: validators pull guaranteed transactions from a dedicated mempool, isolated from public traffic.
  • Validator-level reservation: each validator reserves a predefined portion of every block’s gas capacity for the guaranteed lane. Deterministic inclusion falls out of this.
  • Dedicated RPC nodes: the Guaranteed Blockspace API routes transactions through isolated RPC endpoints, so submission latency doesn’t spike with public RPC load.
The result, for an enrolled partner:
  • Exclusive routing path: submissions don’t compete with public mempool traffic.
  • Guaranteed inclusion: capacity is reserved in every block regardless of network congestion.
  • No decentralization trade-off: validator openness and network participation are preserved; the guarantee lives alongside the public lane, not above it.
  • Reliable on-chain performance for business-critical operations, even under load.
