TROPIC01 is a programmable secure element from Tropic Square intended for device integration. Assessment must distinguish the part number, factory configuration, firmware versions and protections of the complete product.
The main TROPIC01 documentation describes the RISC-V processor and SPECT cryptographic coprocessor. Published RTL, firmware and security architecture provide review materials. This does not mean every internal block of every shipped version is public or independently verified. [Tropic Square — TROPIC01 documentation]
The Part Numbers table separates updatable application and SPECT firmware from permanent factory settings and the certificate chain. For example, TR01-C2P-T202 lists default versions 0.5.0 and 0.3.1. The part number is therefore more than a trade name; firmware can later change. [Tropic Square — Part numbers and firmware versions]
libtropic is an SDK for integrating TROPIC01 into an application. The host library version is not the version of firmware inside the chip. Part documentation matches firmware with the corresponding API and datasheet; updates must preserve this relationship.

In its 3 June 2026 report, Ledger Donjon identifies commercial samples with bootloader v2.0.1 and an Ed25519 verification bypass through laser fault injection. This is a physical laboratory test, not a remote attack or a mathematical break of Ed25519. [Ledger Donjon — TROPIC01 laboratory evaluation, June 2026]
The manufacturer distinguishes storing attacker firmware in TROPIC01 memory from executing it. Verification on each boot requires another physical fault; modified data remaining in memory does not itself ensure persistent code execution after power-off.

Tropic Square states that initial Ledger Donjon testing did not defeat MAC-and-Destroy, but subsequent internal analysis and further independent tests confirmed a path around that protection. An initial unsuccessful test does not prove an attack impossible; the manufacturer is temporarily withholding technical details. [Tropic Square — Firmware verification vulnerability and updates]
The 2026 security disclosure recommends disabling maintenance mode, which increases attack complexity without eliminating it. The manufacturer describes a hardened hardware revision planned for late 2026. A plan is not an already delivered fix or a property of all older chips.

Trezor distinguishes the TROPIC01 attack from other Trezor Safe 7 protection layers, including PIN protection. A component's condition is not automatically that of the entire wallet. Conclusions must identify the product, revision and test scope; openness is not immunity. [Trezor — TROPIC01 component vulnerability]
