Pricing Compared
Starting price reflects the lowest paid tier, not the full cost for every team size or usage level.
Core SDKs and data access are free and open source
Very low latency and high data correctness for on-chain queries
Single API covers 225-plus networks instead of separate integrations
Self-hosting option available for teams wanting full control
Used in production by well-known DeFi protocols managing billions in TVL
Cons
Cloud pricing is usage-based and less predictable than flat subscription tools
Recent acquisition by Rezolve Ai introduces uncertainty about product direction
Primarily targeted at Web3 and blockchain developers, not a general-purpose tool
Requires technical setup and indexing knowledge to get full value
Company size and support structure post-acquisition are not publicly detailed
trumailo
Pros
Real SMTP handshake verification, not just syntax/MX checks, which catches more genuinely undeliverable addresses
Sub-10ms cached response times make it usable inline in a signup or checkout flow, not just for batch list cleaning
Provider-agnostic — works alongside SendGrid, Resend, Postmark, SES, Mailgun, and other ESPs rather than locking you into one
Free public beta tier with no credit card required, plus a 30-day money-back guarantee once paid plans launch
Cons
Specific paid-tier pricing isn't published — you have to sign up or contact sales to see numbers
Still in public beta (v0.5 per the company), so pricing, SLAs, and the feature set are subject to change
No independent third-party security certifications yet — SOC 2 and ISO 27001 are described as roadmap items, not current certifications
Company is small and self-described as a young/internal-tool-turned-product, so long-term track record is limited
Use Cases
SQD
DeFi protocol data indexing — Protocols index on-chain events like swaps, deposits, and liquidations in real time to power dashboards and risk systems.
Blockchain analytics platforms — Analytics products query historical and real-time on-chain data across many networks through a single API instead of managing separate RPC integrations.
AI agents needing on-chain data — AI agents use validated, low-latency on-chain data feeds to make trustworthy decisions involving blockchain state.
