Fair, capped, transparent.
Fixed supply of 6.15B XPRO. Majority allocated to the public presale — no insider unlock at TGE.
Five subsystems. Each faster than Solana.
XPRO learns from Solana's design and replaces each subsystem with a version engineered to remove the specific bottleneck observed in three years of production data.
Benchmarks don't lie.
Testnet on 200 globally distributed c7i.8xlarge validators across 8 regions.

| Aptos | 6,800 | 0.95 s | $0.00010 |

What XPRO is, why it exists, and the design philosophy behind the fastest permissionless Layer 1 ever shipped.
The thesis
Public blockchains are still throughput-bound. Ethereum L1 settles ~17 TPS with 12.8-minute economic finality. Solana clears ~2,300 TPS with 12.8-second finality. Aptos, Sui and Monad push the curve further, but every existing design still trades one of {throughput, latency, decentralization} for the others. XPRO is built on the observation that the trade-off is implementation-bound, not theoretical. By collapsing the consensus clock, propagation, execution and state layers into a single integrated stack, XPRO sustains 218,000 TPS at 0.31-second finality across a 200-validator multi-region testnet.
Design principles
- ›Latency is a feature, not a benchmark. Sub-400ms finality is the design target — every layer is shaped around it.
- ›Parallelism by default. Execution is optimistic with Block-STM conflict detection, not single-threaded.
- ›Verifiable everywhere. Verkle commitments, KZG cold bundles and DAS sampling let any light client verify state without trusting an indexer.
- ›Open spec, full audits, full reports. No exec-summary-only PDFs.
- ›Predictable economics. Fixed supply, transparent vesting, in-protocol MEV redistribution.
Who XPRO is for
Builders of latency-sensitive applications: high-frequency on-chain markets, real-time games, payment rails, AI agent settlement, RWA venues, and any consumer app where a 12-second confirmation is unacceptable. If your product can not survive on a 1-second tail, XPRO is the substrate.
