```go

  import "github.com/bytemare/secp256k1"

```

This package implements the secp256k1 prime-order elliptic curve group with

- [RFC9380](https://datatracker.ietf.org/doc/rfc9380/) hash-to-curve capabilities

- [complete addition formulas](https://eprint.iacr.org/2015/1060.pdf)

- formally verified scalar and field arithmetics provided by [Fiat-Crypto](https://github.com/mit-plv/fiat-crypto)

- square root in the field and inversions generated by [addchain](https://github.com/mmcloughlin/addchain)

- great effort for constant-time operations where possible

- no external dependencies outside the standard go library
