Business Outcomes: Why Gasless Transactions Matter
Meta-transactions on NEAR and Flow aren't just a technical feature—they are a strategic lever for user acquisition and retention. We engineer these solutions to deliver measurable business results.
01
Eliminate Onboarding Friction
Remove the need for users to purchase native tokens before their first interaction. We implement sponsored transaction pools and relayers to onboard users in one click, increasing conversion by up to 70%.

Frequently Asked Questions on Gasless Engineering
Get clear answers on how Chainscore Labs delivers secure, scalable meta-transaction infrastructure for NEAR and Flow.
A standard gasless relayer and sponsor wallet deployment takes 2-4 weeks from kickoff to mainnet. This includes architecture design, smart contract development, frontend SDK integration, and security review. Complex multi-chain or custom fee logic can extend this to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
