Echooo WaaS provides a full-featured wallet SDK, offering capabilities such as key generation, signing, transaction, quote retrieval, token addition, and token trading, to help you minimize development time and achieve fast integration.
Echooo WaaS provides an isolated environment for each project, distinguishing wallets for each project through unique partner verification, ensuring that the wallet in your application is unique.
Echooo WaaS provide a non-custodial wallet without mnemonic phrases or private keys. By leveraging MPC TSS technology, the key is divided into three pieces, with users retaining two, resulting in a fully decentralized wallet.
With Echooo WaaS,users have full control over their wallet, with no single point of failure. Even if your phone is lost or the app is uninstalled and reinstalled, your wallet can still be recovered.
Echooo WaaS employs advanced security measures such as MPC with TSS to safeguard user wallets. Our upgraded MPC TSS solution guarantees the security of keys, offering a robust solution for key management and protection.
Echooo WaaS provides a 3-of-2 three-party TSS system, where users hold two secret Keys, ensuring decentralization and security.
Echooo WaaS utilizes Trusted Execution Environments (TEE) to ensure the security of key fragments. The key generation and signing processes take place within an AWS enclave, providing an exceptionally secure and isolated computational environment. Guarantees that no secrets from the wallet will be leaked during any operation.
After the loss of key fragments held by the user, Echooo's MPC TSS solution provides a key refresh feature. This feature ensures that, while maintaining the same address, users can regenerate the complete set of three key fragments with just one fragment held by the user and one fragment stored by Echooo.
MPC SSS (Shamir's Secret Sharing) provides a distributed key storage solution.
In the SSS mode, the key is divided into multiple fragments and distributed among intermediaries. When key signing is required, participants retrieve their key fragments and combine them at the intermediary to reconstruct the complete key for signing.
MPC SSS effectively addresses the issue of key storage by distributing the risk among multiple parties. However, it still relies on intermediaries for key recovery or distribution, and does not fully resolve the problem of centralization.
MPC TSS (Threshold Signatures Scheme) improves upon the limitations of SSS by eliminating intermediaries. In MPC TSS, participants collectively generate the wallet key without the need for intermediaries. Each participant holds a key fragment, and during signing, they collaboratively perform distributed signing without intermediaries or knowledge of each other's identities and key information.
This approach achieves true decentralization of keys, ensuring that users have complete control over their wallets.
