Everything the table draws on continues here: how firm the #1 is, the per-criterion arithmetic behind each score, who pays ChainChoice, and the full guide to choosing.
Direct answer
What is the best seed phrase backup in 2026?
BitBox Steelwallet ranks #1 overall for seed phrase backup on ChainChoice. Two engraved stainless sheets, 12 words each, marked with an included automatic punch. It holds that rank under an affiliate-blind methodology scored across 4 published, weighted criteria — the code that ranks providers physically cannot read affiliate payouts (CI-enforced), so a payout can't move a rank. The verdict re-computes on every fee change, incident, or regulatory action; full reasoning and the audit receipt are below.

Each bar is the score on that criterion’s own 0–10 scale, never rescaled to the pool. The dark line is the best any product here reached on that axis. Wt is the most the criterion can add to the 86-point weighted total. Pts is weight × score × 32; the sum is the methodology score, and each weighted point behind the leader costs 2.6 on the displayed score. how these are weighted

Why BitBox Steelwallet leads this category right now
Two engraved stainless sheets, 12 words each, marked with an included automatic punch. Strongest on whether the real landed price is on the page (10/10): BitBox's shop page currently answers with a browser challenge; its last readable version (6 August 2026) lists the Steelwallet at €58.50 including 19% VAT, with free shipping from a German warehouse and the punch in the box. The figures are not re-confirmed. Weakest on what you can store and recover (6/10): BitBox's product page currently answers with a browser challenge; its last readable version (6 August 2026) describes punching the first four letters of each BIP-39 word, 12 words per sheet, for 12, 18 or 24-word seeds. Lopp's heat test calls the result highly readable.

Main tradeoff
The A grade is from May 2019 - seven years old - and Shift Crypto quotes that review on the product page as current evidence. Nobody neutral has destroyed a Steelwallet bought from shop.bitbox.swiss. Note also that the free-shipping promise is written in German and describes dispatch from a German warehouse, so buyers outside that lane should not assume it applies to them; the page states no shipping figure for anyone it does not.

Recommendation summary
What should decide this category
Has a neutral third party actually destroyed this product, and what grade did it get?
Is the quoted temperature a test result, or just the melting point of the metal?
If it survives a fire, can the phrase still be read out of it?

SEEDPLATE 24 Words
Single 2mm etched steel plate, 12 words per side, marked with a separately sold centre punch.
Single 2mm etched steel plate, 12 words per side, marked with a separately sold centre punch. Strongest on where the fire number comes from (10/10): SEEDPLATE's site publishes no temperature figure at all and links the words 'Third-party destruction test results' straight to Jameson Lopp's independent review, in which the plate earned A grades for heat, acid and crush. Weakest on whether the real landed price is on the page (5/10): The store lists the plate at $59.97 and the center punch needed to mark it separately at $14.99, $74.96 for a usable unit; the page states neither a shipping cost nor a tax basis, so the landed price appears only at checkout. Published price: "IN-STOCK $69.99 $59.97 SEEDPLATE® 24 Words" with "Single 24 word plate, 12 words per side!

Coldbit Steel
One 4mm AISI 304 plate under a 2mm cover, seed hand-stamped as full words.
One 4mm AISI 304 plate under a 2mm cover, seed hand-stamped as full words. Strongest on what you can store and recover (9/10): Coldbit Steel stores each seed word in full, up to eight letters, stamped into a single stainless plate, with a spare line for a 25th word and SLIP-39 support; after Lopp's 20-ton crush test the data survived but was 'Hard to read'. Weakest on where the fire number comes from (6/10): Coldbit claims resistance to 'extreme temperatures (up to 1200 C)' for its AISI 304 plates, below that steel's 1400-1450°C melting range, but states no test method and does not cite Lopp's independent test, in which it earned straight A grades. Published price: "Regular price €89,00 EUR" for the "A-Z Stamps + Jig Included" variant and "€69,00" for "No Stamps No Jig", with "Taxes included. Discounts and shipping calculated at checkout." (fetched 2026-09-27; unchanged since 2026-08-06).

Hodlr Shield — Stealth Titanium Heart 24
Twenty-four acid-etched titanium disks riveted inside a milled capsule, marked by centre punch.
Twenty-four acid-etched titanium disks riveted inside a milled capsule, marked by centre punch. Strongest on whether the real landed price is on the page (10/10): Hodlr prices one Stealth Titanium Heart 24 at €239 with 'Tax included. Free shipping worldwide.' on the product page, and the item shows as in stock; the shipping policy adds that customs are pre-paid for most countries. Weakest on where the fire number comes from (3/10): Hodlr states 'Fireproof up to 1,650°C / 3,000°F', the same figure it gives as the titanium disks' melting point, and sets it against house fires without a method or an independent citation; Lopp recorded this vendor's 2021 claim as 1,350 °C. Published price: "Sale price €239,00" with the pack ladder "Solo-Pack" and "3-Pack" priced "€239,00" and "€569,00", and "Tax included. Free shipping worldwide." (fetched 2026-09-27; every string unchanged since 2026-08-06).
