Overview

SparkVault is a non-custodial wallet optimised for cheap, efficient on-chain trading. It concentrates on the busiest EVM chains and layer-2s rather than chasing breadth, using that focus to deliver tight routing and low costs across its 18 supported networks.

Fees & costs

Cost is SparkVault's headline. Its swap aggregator charges a flat 0.15%, the lowest here, and layers on gas batching plus fee-market optimisation to trim on-chain expense. MEV-protected routing on supported chains shields larger trades from sandwich attacks, which can save more than the fee itself.

Security

Keys stay on-device with biometric unlock and hardware-wallet pairing. SparkVault's routing contracts are audited, and MEV protection doubles as a security feature by reducing predatory ordering. It lacks native multisig, so treasury-scale users may want a complementary setup.

Who it's for

SparkVault suits active traders and cost-sensitive users who live on major EVM chains and swap frequently. Those needing Bitcoin, Solana, Cosmos, or multisig will find the coverage too narrow, but for low-cost EVM trading it is excellent value.
