@cosmjs/amino — Greenflagged

Helpers for Amino based signing.

Supply chain provenance

Status for the latest visible version.

No SLSA provenance npm registry signatures gitHead linked

Without SLSA provenance there is no cryptographic link between this tarball and the public source — the axios compromise (March 2026) relied on exactly this gap.

Accepted risks

Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
provenance	no-provenance	AI (provenance): Package predates Sigstore provenance adoption; publisher has strong track record. Low risk for this established ecosystem package.	ai	2026/04/22
provenance	missing-githead	AI (provenance): CosmJS is a well-established project; missing gitHead reflects a publish environment change, not a supply chain compromise. Publisher has 168 approved packages and 0 rejections.	ai	2026/04/22
source-diff	encoded-string-file:build/testutils.spec.js	AI (source-diff): Long strings are Bech32-encoded public keys used as test fixtures in a Cosmos cryptography library — not obfuscated payloads.	ai	2026/04/22
source-diff	encoded-string-file:build/testutils.spec.d.ts	AI (source-diff): Long strings are Bech32-encoded public keys in TypeScript declaration test fixtures — not obfuscated payloads.	ai	2026/04/22
bogus-package	bogus-package	AI (bogus-package): Signals (short README, no keywords) are cosmetic and not indicative of malicious intent for this well-known CosmJS library.	ai	2026/04/22
provenance	publisher-changed	AI (provenance): Publisher change from webmaster128 to willclarktech occurred in 2021 as a legitimate CosmJS org transition; willclarktech has 86 approved packages and 0 rejected since then.	ai	2026/04/22
dependencies	unvetted-dep:@cosmjs/encoding	AI (dependencies): Sibling package from the same CosmJS monorepo, published by the same trusted maintainer.	ai	2026/04/21
dependencies	unvetted-dep:@cosmjs/crypto	AI (dependencies): Sibling package from the same CosmJS monorepo, published by the same trusted maintainer.	ai	2026/04/21
dependencies	unvetted-dep:@cosmjs/utils	AI (dependencies): Sibling package from the same CosmJS monorepo, published by the same trusted maintainer.	ai	2026/04/21
dependencies	unvetted-dep:@cosmjs/math	AI (dependencies): Sibling package from the same CosmJS monorepo, published by the same trusted maintainer.	ai	2026/04/21
typosquat	typosquat.levenshtein:pino	AI (typosquat): @cosmjs/amino is a scoped Cosmos blockchain package with no relation to 'pino'. The Levenshtein match is purely coincidental; this is a stable false positive for this package.	ai	2026/04/21
