Amp

Amp is an Ethereum-based digital collateral token (an ERC-20 fungible token extended with ERC-1400-style partitions and ERC-777-style operator semantics) designed to collateralize and instantly settle value transfer worldwide, most notably as the collateral layer behind Flexa payments. The AMP contract (0xff20817765cb7f73d4bde2e66e067e58d11095c2) supports partitioned staking, registered collateral managers, and operator authorization, and has been independently audited by ConsenSys Diligence (June 2020) and Trail of Bits (August 2020). Amp is smart-contract-only and exposes no REST/HTTP API; its published "API reference" documents the on-chain contract interface. The project is stewarded by the Acronym Foundation and was backed by Pantera Capital.

Amp is profiled on the APIs.io network. Tagged areas include Company, Crypto, Blockchain, Ethereum, and Collateral Token.

Amp’s developer surface includes documentation, API reference, support, engineering blog, and 8 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/amp: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
