Send funds	Transfer SOL	Transfer native currency
Sponsor gas or fees	Hosted Paymaster (API key)	ERC-4337 with a compatible bundler

Each chain view describes its own prerequisites and supported flows. EVM sponsorship requires a compatible bundler and paymaster; its Rust and Python examples use the local test fixture.

Hosted integrations
